Qonscious Framework Enables Agnostic Quantum Backend Evaluation

Researchers have developed a new way to compare the performance of quantum computers from different manufacturers, addressing the challenge of widely varying proprietary metrics. The team proposes a Figure of Merit (FoM) based on Grover’s algorithm, designed as an algorithmic stress test that evaluates quantum backends by combining success probability with penalties for errors, yielding a unified score across diverse hardware. This metric accounts for factors static measurements like coherence times and gate error rates often miss, including dynamic variability across successive executions and the impact of the transpilation process. Implemented on the Qonscious framework, a conditional execution platform that readily provides the polymorphic adapters needed to execute the same metric in…
