SOFT: High-Performance Quantum Circuit Simulator
Analysis
This paper introduces SOFT, a new quantum circuit simulator designed for fault-tolerant quantum circuits. Its key contribution is the ability to simulate noisy circuits with non-Clifford gates at a larger scale than previously possible, leveraging GPU parallelization and the generalized stabilizer formalism. The simulation of the magic state cultivation protocol at d=5 is a significant achievement, providing ground-truth data and revealing discrepancies in previous error rate estimations. This work is crucial for advancing the design of fault-tolerant quantum architectures.
