How Much Money Do You Waste on Unnecessary Quantum Computer Measurements?
Time on a quantum computer is rented by the shot, meaning one run of a circuit. Every shot comes back noisy. The accelerated variational quantum eigensolver, or AVQE, lives with that: it puts a question to the machine, infers an answer from the noise, and repeats until the answers settle. Making that inference on whole distributions rather than approximating it converges in 44% fewer shots. Enter how many runs you do and what your provider charges you.
Variational Runs Per MonthHow many times you drive the eigensolver to convergence in a month, across all molecules or Hamiltonians.

Target Precision, Negative ExponentThe exponent of your target precision, so 4 means 10 to the minus 4. The published figure was measured at that setting. The shot requirement grows steeply as you tighten it.

Price Per ShotWhat your provider bills for one measurement. The default is the lowest published rate on the AWS Braket rate card, $0.000425 a shot on Rigetti Cepheus, read August 2nd 2026. Rates differ by more than an order of magnitude across providers and are usually negotiated, so take yours from your own invoice.
Price Per Circuit MappingSome providers bill a per-task fee on top of per-shot. The default is the AWS Braket rate card per-task price, $0.30, the same on every quantum processor that service offers, read August 2nd 2026. Set it to zero if your provider charges none.
Where the Classical Step Runs TodayThe published comparison is against the first, implemented by hand on an Intel Xeon. Rejection filtering is chosen because it is cheap enough to run beside a quantum device, so it is not a naive baseline.
Engineer-Days to Maintain ItWhat you spend keeping the classical inference step working. The default follows the program you picked. The brief reports 14 lines of code against 63. Only you can say what that is worth in your own team.
Override the speedup
This calculator's figures rest on one measured multiple, cited
with its baseline under the result. If you have measured your own, on your own workload, enter it
here and the arithmetic follows it. Nothing leaves the page. The citation under the figures still
reports what Signaloid measured, a banner above the result says the numbers are yours, and the
exported card and the quote mail both record the substitution. Clear the field to go back.
There is no single multiple to override here. This
calculator's figures rest on several separately measured quantities rather than on one speedup.
Each is cited with its own baseline under the result. Overriding one of them alone would give
a figure that follows from no measurement, so the field the other calculators carry is absent.
