Virtual Quantum Markov Chains

no code implementations4 Dec 2023 Yu-Ao Chen, Chengkai Zhu, Keming He, Mingrui Jing, Xin Wang

In this work, we propose the concept of virtual quantum Markov chains (VQMCs), focusing on scenarios where subsystems retain classical information about global systems from measurement statistics.
