摘要

Quantum computer operations, called quantum gates, include qubit rotations, entanglement operations, and measurements, each of which is essential for the implementation of advanced quantum algorithms. However, the effect of phase noise in control operations has not yet been extensively studied. We present a practical phase noise model for performing simulations with control signals affected by phase noise as close as possible to that obtained from a real system.
