It is the #QuantumAnalogue to the #ComplexityClass #BPP.

A #DecisionProblem is a member of #BQP if there exists a #QuantumAlgorithm (an #algorithm that runs on a #QuantumComputer) that solves the decision problem with #HighProbability and is guaranteed to run in #PolynomialTime.

A run of the algorithm will correctly solve the #DecisionProblem with a probability of at least 2/3.

#BQP can be viewed as the languages associated with certain bounded-error uniform families of quantum circuits.

...
Alternatively, one can define BQP in terms of #QuantumTuringMachines.

In the honor of my two esteemed colleagues (@abiteboul.com and Victor Vianu), the Abiteboul–Vianu theorem is now formalized and machine-proofed as part of my descriptive-complexity Lean 4 library.

A dual mind often leads to uncertainty or wrong decisions
It is best to speak with an experienced person at that time.
