The Picture of Dorian Qubit
A short comedy of probability, possibility, money, and the machine that was always five years away
There are only two tragedies in technology. One is not getting the machine you were promised. The other is getting another roadmap.
I. The Dinner
At half past eight on a Thursday evening, in a private dining room so expensive that the butter had been given a biography, Sir Peregrine Vale announced that the quantum computer had finally arrived.
Nobody asked where it was.
This was considered impolite.
The room belonged to the Club of Imminent Things, an institution founded in London for technologies that were always about to transform civilisation and preferred not to be disturbed by evidence.
The walls were lined with portraits of previous members: nuclear fusion, flying cars, paperless government, and a particularly handsome photograph of a hydrogen economy that had been arriving shortly since before several of the diners were born.
At the far end hung an empty gilt frame.
The brass plaque beneath it read:
**THE QUANTUM COMPUTER
ARRIVING SOON**
“Gentlemen,” said Sir Peregrine, lifting his champagne, “history has changed.”
“Again?” asked Lady Probability.
She was the only woman at the table and the only person present whose occupation did not improve when nobody checked the arithmetic.
Sir Peregrine smiled patiently.
“My dear Lady Probability, you must learn to distinguish scepticism from vision.”
“I do,” she said. “Vision is what people call a forecast after removing the confidence interval.”
The venture capitalist beside her coughed into his Burgundy.
Sir Peregrine continued.
“Quantum computing is here.”
“Splendid,” said Lady Probability. “Where?”
There was a silence.
Professor Septimus Entangle, chairman of the evening, adjusted his spectacles.
“One must not be literal about transformative technology.”
“I had thought literal existence one of the less ambitious requirements of machinery.”
“There are processors.”
“There are also propellers,” she replied. “I do not therefore claim to own an aircraft carrier.”
Sir Peregrine frowned.
“You are playing with words.”
“No,” said Lady Probability. “You are. I merely noticed.”
II. The Machine in the Next Room
After the soup, Sir Peregrine announced that the Club had acquired a quantum computer.
This created considerable excitement.
Several guests instinctively checked the share prices of companies they had never understood.
Lord Venture, whose genius consisted largely of entering rooms after other people had taken the risk, leaned forward.
“You have one here?”
“Naturally.”
“Can we see it?” asked Lady Probability.
Sir Peregrine looked wounded.
“It is in the next room.”
“Then let us go to the next room.”
“It is not currently accessible.”
“Locked?”
“Calibrating.”
“For how long?”
“That is not the relevant question.”
Lady Probability looked at the empty gilt frame.
“It has been the relevant question for thirty years.”
Professor Entangle intervened.
“You are thinking classically.”
“I find it convenient when opening doors.”
The professor smiled the smile of a man who had discovered that condescension requires less energy than explanation.
“The machine exists in a delicate state.”
“So does the soufflé. We may nevertheless inspect it.”
A waiter entered carrying twelve immaculate soufflés.
Every one of them existed.
This was awkward.
III. Lord Possibility
The doors opened and Lord Possibility arrived forty minutes late, apologising to nobody.
He was tall, silver-haired, beautifully tailored and employed by three consultancies, two governments, four advisory boards and a conference in Davos whose subject changed annually but whose invoice did not.
He kissed Lady Probability’s hand.
“Still ruining perfectly good futures with arithmetic?”
“Still selling perfectly good possibilities as appointments?”
“My dear, possibility is everything.”
“No. It is the beginning of everything. Unfortunately, you invoice at the beginning.”
Lord Possibility laughed.
“That is why I am solvent.”
Sir Peregrine poured him champagne and brought him up to date.
“We were discussing the arrival of quantum computing.”
“Wonderful,” said Lord Possibility. “I have been discussing its arrival since 2003.”
“And has it arrived?”
“More than ever.”
Lady Probability tilted her head.
“That is not an answer.”
“It is much better than an answer. It is a trend.”
“Towards what?”
“Scale.”
“How much?”
“Increasing.”
“Useful?”
“Promising.”
“Reliable?”
“Improving.”
“Economic?”
“Transformative.”
“Present?”
“Imminent.”
Lady Probability nodded.
“I see. The machine is conjugated entirely in adjectives.”
IV. The Roadmap
Professor Entangle called for the roadmap.
Two junior analysts entered carrying a projection screen with the solemnity of altar boys.
Upon it appeared an arrow.
The arrow began in the present and rose confidently toward the upper right.
Nothing in finance, technology or public policy has ever lost money while travelling toward the upper right.
“Observe,” said Sir Peregrine.
“I am observing an arrow,” said Lady Probability.
“It represents progress.”
“It represents PowerPoint.”
“Here,” he continued, “we have today’s devices. And here—” he pointed several inches upward and right “—we have useful fault-tolerant quantum computing.”
“How far apart are those inches?”
“Technologically?”
“Chronologically.”
Sir Peregrine hesitated.
Lord Possibility rescued him.
“Roadmaps are not predictions.”
“How fortunate,” said Lady Probability. “Investors often mistake the dates for dates.”
Professor Entangle cleared his throat.
“IBM, for example, publicly describes Starling as planned for 2029, with two hundred logical qubits and one hundred million quantum gates.”
Lady Probability brightened.
“Excellent.”
“You agree?”
“Entirely. It is planned for 2029.”
“Precisely.”
“Which is an unusually elaborate way of saying it is not here.”
Sir Peregrine sighed.
“You cannot use the roadmap against the roadmap.”
“Why ever not? It is the only document in the room honest enough to put the miracle in the future.”
Lord Possibility smiled.
“My dear, you lack imagination.”
“No. I merely insist that tomorrow should wait until tomorrow before introducing itself as today.”
V. Willow
At this point the youngest man at the table, Crispin Ledger, spoke.
Crispin was twenty-seven and had founded a company called Qynapse, which had no revenue but possessed seventeen partnerships and a brand video involving a galaxy.
“What about Willow?” he said.
Everyone turned.
Crispin had been waiting all evening for someone to ask what about Willow.
“Google’s Willow chip,” he continued. “They demonstrated error correction and a computation they said would take a classical supercomputer an absurdly long time.”
“Indeed,” said Professor Entangle. “A major technical result.”
Lady Probability nodded.
“A result I am perfectly happy to admire.”
Crispin looked disappointed.
“Then you concede quantum computing exists.”
“No. I concede that an experimental quantum processor performed an experimental quantum task.”
“That is a quantum computer.”
“Then a wind tunnel is an airline.”
Crispin blushed.
Professor Entangle intervened gently.
“Google itself says Willow ‘paves the way’ to a useful, large-scale quantum computer.”
Lady Probability smiled.
“How wonderfully considerate of them.”
“Meaning?”
“The road is real. The paving may be excellent. But a road which paves the way to Paris is not Paris.”
Lord Possibility poured more wine.
“Metaphors are dangerous things.”
“Only when they arrive before the machine.”
VI. The Portrait
After dessert, the club secretary announced the unveiling of the portrait.
The empty gilt frame was carried from the wall and replaced by an enormous canvas hidden beneath velvet.
Sir Peregrine took the cord.
“Ladies and gentlemen, Professor Dorian Qubit.”
He pulled.
The cloth fell.
The portrait showed a magnificent machine.
It stood in a cathedral of polished metal and blue light, surrounded by engineers gazing upon it with the religious devotion normally reserved for saints and successful grant applications.
Along the bottom, in gold leaf, were the words:
THE FIRST USEFUL FAULT-TOLERANT QUANTUM COMPUTER
“Beautiful,” whispered Crispin.
Lady Probability approached the canvas.
“When was it painted?”
“Originally?” asked Sir Peregrine.
“There has been more than one?”
“Naturally. We update it.”
“Why?”
Professor Entangle looked uncomfortable.
“The dates change.”
“Ah.”
Behind the new canvas, Lady Probability noticed a second frame leaning against the wall.
She pulled it out.
The same machine appeared, slightly less elegant.
The inscription said 2025.
Behind that stood another.
2030.
Another.
Ten years away.
Another.
Five years away.
Another.
Within the decade.
The room had become quiet.
Lady Probability examined the stack.
“Dorian Gray had the decency to keep only one embarrassing portrait.”
Sir Peregrine bristled.
“Those represent earlier expectations.”
“No,” she said. “They represent a remarkable technology for moving the present without moving the machine.”
VII. The Demonstration
There came a knock.
A technician entered.
“Sir Peregrine, the system is ready.”
The room erupted.
Lord Venture stood so quickly he spilled a wine older than Crispin.
“At last!”
Even Lady Probability appeared interested.
They were led through a corridor, down a lift, across a security vestibule and into a laboratory colder in spirit than in temperature.
Behind glass stood the machine.
It was magnificent.
Gold cylinders descended like chandeliers designed by a jeweller with military funding. Cables blossomed everywhere. Screens glowed. Pumps hummed. Men with badges looked worried in twelve different specialisms.
Lord Possibility whispered, “My God.”
Lady Probability said, “It is very pretty.”
The technician explained the demonstration.
There would be a prepared circuit.
There would be calibration.
There would be repeated runs.
There would be error mitigation.
There would be classical processing.
There would be interpretation.
There would be a comparison.
There would, eventually, be a result.
Sir Peregrine beamed.
“You see?”
“I see an experiment.”
“A computation.”
“A prepared experiment which computes something.”
“That is what computers do.”
Lady Probability turned toward him.
“My pocket calculator does not require a research team to explain why seven times eight is a milestone on the path to fifty-six.”
The technician coughed.
“This is rather more complicated.”
“Exactly,” she said. “Which is why we should describe it precisely rather than promote it prematurely.”
Sir Peregrine looked wounded.
“You are impossible to impress.”
“Not at all. I am impressed by experiments. I merely refuse to award them honorary doctorates in products.”
VIII. Majorana Arrives in a Taxi
When they returned upstairs, a courier had delivered a large silver box.
On top sat a press packet.
Crispin seized it.
“Microsoft Majorana.”
Lord Venture brightened again.
“The topological one?”
“Yes.”
Crispin began reading triumphantly.
“Microsoft called Majorana 1 the first quantum processor powered by topological qubits and described it as a leap—”
Lady Probability held out her hand.
“May I?”
Crispin reluctantly passed her the page.
She read for a moment.
“How lovely.”
“There!” said Crispin.
“It says ‘toward practical quantum computing.’”
“Yes.”
“Toward.”
“You are doing it again.”
“I am doing nothing. Their preposition is doing all the work.”
Lord Possibility laughed despite himself.
“You cannot prosecute an industry with grammar.”
“Of course one can. Most fraud enters through adjectives and escapes through the future tense.”
IX. The Consultant
At eleven, Dr Felix Strategy arrived.
He had been delayed by a quantum-readiness workshop.
“For whom?” asked Lady Probability.
“A shipping company.”
“Do they own a quantum computer?”
“No.”
“Does anyone?”
Dr Strategy laughed professionally.
“That is not the point.”
“Excellent. We are making progress. What is the point?”
“Readiness.”
“For what?”
“Quantum.”
“Which does what for the shipping company?”
“Potentially optimises routing.”
“Better than their existing systems?”
“Potentially.”
“At lower cost?”
“Potentially.”
“At useful scale?”
“Potentially.”
“Today?”
Dr Strategy looked offended.
“Obviously not today.”
Lady Probability smiled.
“And what did you charge them today?”
The room laughed.
Dr Strategy did not.
Consultants dislike jokes whose punchline appears in accounts payable.
X. Schrödinger’s Invoice
Lord Possibility proposed a game.
Each guest was to write down the year in which a commercially useful, fault-tolerant quantum computer would actually perform an economically valuable task beyond the best practical classical alternative.
The slips were folded into a silver bowl.
Sir Peregrine wrote 2029.
Crispin wrote 2028.
Professor Entangle wrote “application dependent.”
Dr Strategy wrote “clients should prepare now.”
Lord Venture wrote nothing, because investors prefer optionality.
Lady Probability wrote a question mark.
“Cowardice,” said Sir Peregrine.
“Calibration.”
“You refuse to predict.”
“No. I refuse to counterfeit precision.”
Lord Possibility raised his glass.
“But surely you assign some probability.”
“Of course.”
“Then give us the probability.”
“To which machine, architecture, task, error rate, cost threshold, scale, year and classical comparison?”
There was a pause.
“You see,” she said. “Probability is very tiresome. It insists on asking what proposition we are actually discussing.”
“Possibility is much friendlier,” said Lord Possibility.
“That is why you are invited to conferences.”
XI. The Unicorn
At midnight, the club doors opened and a white unicorn walked into the dining room.
Nobody screamed.
This was the Club of Imminent Things.
They had seen stranger pitch decks.
The unicorn was magnificent: ivory coat, silver mane, a horn like polished moonlight.
It walked to the centre of the room and ate a floral arrangement worth four hundred pounds.
Sir Peregrine stared.
“Good God.”
Lady Probability stood.
“At last.”
“What?”
“A unicorn.”
Professor Entangle frowned.
“We cannot know that.”
“It has walked into the room.”
“Appearances can mislead.”
“It has a horn.”
“Could be prosthetic.”
“It is eating the roses.”
“That merely demonstrates herbivorous behaviour.”
Crispin circled it suspiciously.
“Has it been peer reviewed?”
Lord Possibility folded his arms.
“There is no agreed benchmark for unicorn utility.”
Dr Strategy was already typing.
“I can have a Unicorn Readiness Framework by Monday.”
Lady Probability looked around the room.
“How extraordinary.”
“What?” asked Sir Peregrine.
“For quantum computing, an experimental apparatus plus a roadmap is enough to declare the beast arrived. For an actual unicorn standing in front of you, suddenly everyone wants evidence.”
The unicorn sneezed.
Professor Entangle stepped backward.
“That proves nothing.”
“Naturally.”
XII. The Trial
Lady Probability climbed onto a chair.
“I propose a trial.”
Sir Peregrine groaned.
“Of the unicorn?”
“No. Of the word computer.”
The room went still.
“The charge is semantic inflation.”
Lord Possibility clapped.
“I adore trials in which nobody goes to prison.”
“The prosecution submits that the public has been sold an image: a machine which performs useful, scalable, reliable quantum computation of practical economic value. The defence presents experimental processors, specialised tasks, error mitigation, roadmaps and promises.”
Professor Entangle objected.
“That is unfair.”
“Reality often is.”
“You are setting the bar too high.”
“I am setting the bar where the advertisements put it.”
This produced the first genuine silence of the evening.
Lady Probability continued.
“Google says Willow paves the way to the useful machine. IBM says Starling is planned for 2029. Microsoft says Majorana points toward practical quantum computing. These are not the words of sceptics. These are the words of the builders.”
She looked at Sir Peregrine.
“The prosecution rests on the defendants’ prepositions.”
Lord Possibility whispered, “Devastating.”
XIII. The Defence
Professor Entangle stood.
He looked suddenly older.
“May I say something without being roasted?”
“No,” said Lady Probability. “But you may say it.”
He smiled.
“The work is real.”
“I know.”
“The experiments are real.”
“I know.”
“The progress is real.”
“Some of it undoubtedly.”
“Then why ridicule it?”
Lady Probability stepped down from the chair.
“I am not ridiculing the work.”
She pointed toward Dr Strategy.
“I am ridiculing the distance between the work and him.”
Dr Strategy looked personally attacked, which was accurate.
“The scientists say ‘toward.’ Marketing says ‘here.’ Scientists say ‘promising.’ Consultants say ‘transformative.’ Engineers say ‘milestone.’ Investors hear ‘market.’ Researchers say ‘may.’ Headlines print ‘will.’ Someone demonstrates a narrow result, and by lunchtime an airline is told it needs a quantum strategy.”
Professor Entangle sat down.
“That,” he admitted, “can happen.”
“Can?”
“Does.”
XIV. The Portrait Ages
A strange thing then occurred.
The great portrait of Dorian Qubit began to change.
The glowing machine remained young and perfect.
But the date beneath it faded.
2029 became 2031.
2031 became 2033.
Then the date disappeared entirely and was replaced by:
THE QUANTUM ERA
Crispin gasped.
“What happened?”
Lady Probability stared at the canvas.
“It has achieved roadmap maturity.”
The machine in the portrait grew brighter.
The promises around it grew vaguer.
The word computer shrank.
The word ecosystem enlarged.
Soon the engineers vanished from the painting altogether and were replaced by consultants holding tablets.
Then appeared three arrows.
All pointed upward and right.
Lord Venture began applauding.
He could not help himself.
XV. The Morning After
At two in the morning, the party ended.
The unicorn was still there.
It had eaten the centrepiece, two napkins and Lord Venture’s term sheet.
“What shall we do with it?” asked Sir Peregrine.
“Study it,” said Professor Entangle.
“Commercialise it,” said Crispin.
“Advise people about it,” said Dr Strategy.
“Short it,” said Lord Venture.
Lady Probability put on her coat.
“Perhaps,” she said, “we might first establish what it is.”
Everyone looked disappointed.
She walked toward the door.
Sir Peregrine called after her.
“You really believe quantum computing is all nonsense?”
She stopped.
“No.”
This surprised them.
“I believe nonsense begins precisely where the evidence ends and the invoice continues.”
She opened the door.
“Research whatever you like. Build whatever you can. Celebrate every genuine advance. But do not hand me a possibility and demand that I call it a probability. Do not hand me a probability and demand that I call it a product. Do not hand me a roadmap and demand that I call it a machine.”
She glanced back at the portrait.
“And if your computer has spent thirty years arriving, do forgive me if I wait until it reaches the room before offering it champagne.”
XVI. Epilogue: The Press Release
The following morning, the Club of Imminent Things issued a statement.
Historic breakthrough demonstrates transformative progress toward next-generation quantum-enabled computational ecosystems.Last night’s event confirmed significant momentum across the quantum landscape and highlighted the accelerating convergence of hardware, software, error correction, investment, ecosystem readiness and strategic alignment.The Club remains confident that commercially meaningful quantum applications are closer than ever.
No machine had been delivered.
No economically useful problem had been solved.
The unicorn was omitted entirely.
Its existence could not be independently benchmarked.
By lunchtime, however, Dr Strategy had sold three Unicorn Readiness Workshops.
Sir Peregrine had raised a new fund.
Crispin’s company valuation had doubled.
Professor Entangle returned to the laboratory.
And Lady Probability received a note from Lord Possibility.
It contained only one sentence:
My dear, you were right—but fortunately, right has never been a prerequisite for a market.
She laughed, folded the note, and placed it beside the morning paper.
On the front page was a photograph of another golden machine.
The headline read:
QUANTUM FUTURE CLOSER THAN EVER
Lady Probability finished her coffee.
“Of course it is,” she said.
“It has had another day.”
