The Optical Compiler Routed Around Its Own Imperfections
Hardware-aware subcircuit placement raised coincidence rates by as much as 33.2% across the reported benchmarks.
Summary
Hardware-aware subcircuit placement raised coincidence rates by as much as 33.2% across the reported benchmarks.
Linear-optical quantum circuits lose accuracy and photons when phase noise and fabrication imperfections vary across the chip. This compiler incorporates a device’s nonuniform imperfections when mapping subcircuits, selecting placements that reduce their impact rather than assuming uniform hardware. Across the authors’ benchmark suite, the method improved phase-noise robustness and increased coincidence rates by as much as 33.2%. The evaluation demonstrates compilation gains on tested models and devices, not fault-tolerant operation.
