摘要

量子系统的模拟是近期NISQ(噪声中等规模量子)计算设备的旗舰应用之一。在NISQ硬件上,有效地模拟开放量子系统的丰富、非单一动力学仍然是一个挑战。目前开放量子系统的模拟方法采用时间步进的Trotter积公式(“Trotterization”),该公式在模拟时间和系统维度方面的可扩展性很差。本文提出了一种基于时间摄动Kraus算子级数表示的仿真方法。在一类开放量子系统中,这种方法产生了与时间无关的深度电路,可以作为trotter化的理想替代方案,特别是在NISQ器件上。

Trotterless Simulation of Open Quantum Systems for NISQ Quantum Devices

Trotterless Simulation of Open Quantum Systems for NISQ Quantum Devices

The simulation of quantum systems is one of the flagship applications of near-term NISQ (noisy intermediate-scale quantum) computing devices. Efficiently simulating the rich, non-unitary dynamics of open quantum systems remains challenging on NISQ hardware. Current simulation methods for open quantum systems employ time-stepped Trotter product formulas (“Trotterization”) which can scale poorly with respect to the simulation time and system dimension. Here, a new simulation method is proposed based on the derivation of a time-perturbative Kraus operator series representation of the system. A class of open quantum systems is identified for which this method produces circuits of time-independent depth, which may serve as a desirable alternative to Trotterization, especially on NISQ devices.
