Quantum computers need reliable operations beside more qubits
By OnTheRice · Sources and limitations · Report a correction
A 9 October paper reports measurements, resets and feedback on a 100-qubit IBM processor. OTR links these operations with access and manufacturing programmes. Independent useful-work results would strengthen the case; poor repeat tests or excessive control costs would weaken it.

What’s changing?
We connect the OTR data on a 100-qubit feedback experiment with its accounts of quantum access and manufacturing programmes. The 9 October Nature Physics paper reports measurements, resets and conditional feedback on an IBM processor.
Key points
- We would compare circuit depth, error behaviour, feedback delay and reproducibility against a stated classical method. We would ask whether a control technique improves a useful task outside the demonstration.
What could change this view?
- Independent results showing a practical advantage on a clearly defined workload would strengthen the claim. Weak replication or unmanageable control overhead would weaken it.
Bottom line
We would track controlled useful work per run. A physics demonstration can be important without being a general quantum computer or a short-term commercial product.
Its source facts and prices still need independent checks.
Terms in simple English
These explanations help you read this signal. The saved forecast, prices, deadline and outcome rules stay the same.
- Asset or investible
- Something that can be bought or sold, such as a share, bond, fund, currency or cryptocurrency.
- Probability
- An estimate of how likely an outcome is. For example, 60% means about six chances in ten, not certainty.
- Uncalibrated estimate
- A judgement that has not been shown to match real outcomes reliably. It is not a proven success rate.
- Calibration
- Checking whether stated chances match real results across many forecasts. An estimate can still be untested.
- Bayesian framework
- Updating an earlier belief with new evidence. A posterior is the updated estimate; a likelihood ratio compares how evidence fits outcomes. A subjective estimate may have no tested calculation.
- De Finetti framework
- Keeping probability judgements consistent. Related calls may share evidence, so one story must not count as several independent reasons.
- Kolmogorov framework
- Basic probability rules: chances cannot be negative, and separate possible outcomes together total 100%.
How likely is this call? · Three frameworks
This signal has no investible bullish or bearish call. A market-direction percentage does not apply.
Evidence behind this view
Checks whether separate pieces of evidence support the same view.
The OTR sections distinguish experimental control from manufacturing and user-access announcements. The paper's abstract states the experimental target and device scale.
What past price moves show
Compares today’s price moves with recorded past patterns.
Not applicable: this is a technology synthesis, not an investible or price forecast.
Evidence against this view
Shows evidence and risks that could challenge this view.
Control methods may later transfer to more useful algorithms. Failure to establish commercial value in this paper is not proof of no scientific value.
Why the direction changed
Explains recorded changes from expecting a rise to expecting a fall, or the reverse.
Learning review before publication
The supplied direction was retained: No investible directional call.
The supplied synthesis was retained.
Reason: Retain the controlled-operations framing and distinguish the narrow quantum result from the separate Xanadu–GlobalFoundries partnership. Neither establishes broad production capacity.
Lessons considered: Keep the clocks separate; Look for independent evidence; Keep incomplete tests visible; Separate direction from explanation; Use lessons in the next call; Compare matching quantities.
This review belongs to the new draft before publication. Earlier published calls and their original deadlines remain unchanged.
What people say vs the facts
Compares recorded public discussion with checked market facts.
We separate the number of qubits from the workload, quality and outcome of the computation.
How past forecasts performed
Shows recorded forecast results and what they can teach us.
We have not verified completed, matching technology forecasts in the OTR records inspected for this signal. The percentage is an uncalibrated judgement and is not a historical hit rate.
The pre-publication learning review is recorded under “Why the direction changed”, including cases where the supplied direction was retained.

Original research record
We connect the OTR data on a 100-qubit feedback experiment with its accounts of quantum access and manufacturing programmes. The 9 October Nature Physics paper reports measurements, resets and conditional feedback on an IBM processor. It studies a particular chaotic map. Our connection is that meaningful progress needs dependable operations during a calculation, not simply a larger headline qubit count.
We would compare circuit depth, error behaviour, feedback delay and reproducibility against a stated classical method. We would ask whether a control technique improves a useful task outside the demonstration.
Independent results showing a practical advantage on a clearly defined workload would strengthen the claim. Weak replication or unmanageable control overhead would weaken it.
We would track controlled useful work per run. A physics demonstration can be important without being a general quantum computer or a near-term commercial product.
Bayesian · what changed the estimate? We estimate a subjective 65% chance that a one-week technical review will find no demonstrated general commercial advantage in this paper alone. The estimate concerns the scope of the evidence. we have not fitted a prior or evidence likelihoods, so this is not a computed posterior. de Finetti · are the comparisons fair? we treat repeated OTR editions as one underlying source when they reuse a report; our judgement must not gain confidence just from repetition. Kolmogorov · do the numbers agree? for the stated test event, the probability of it occurring and not occurring sums to 100%. None of these checks establishes historical calibration.
