报告简介：

Quantum computers are expected to excel in simulating unitary dynamics, while most applications in scientific and engineering computations involve non-unitary dynamics.

First, we propose a simple method for simulating a general class of non-unitary dynamics as a linear combination of Hamiltonian simulation (LCHS) problems [Phys. Rev. Lett. 2023]. We then propose a variational quantum algorithm for simulating non-Hermitian dynamics, significantly reducing circuit depth and hardware overhead. These results advance the feasibility of simulating realistic open-system dynamics on near-term quantum processors and provide practical tools for quantum simulation in the NISQ era.
