Classical simulability of Clifford+T circuits with Clifford-augmented matrix product states
Zejun Liu, Bryan K. Clark
Determining the quantum-classical boundary between quantum circuits which can be efficiently simulated classically and those which cannot remains a fundamental question. One approa…

Non-equilibrium quantum Monte Carlo algorithm for stabilizer Renyi entropy in spin systems
Zejun Liu, Bryan K. Clark
Quantum magic, or nonstabilizerness, provides a crucial characterization of quantum systems, regarding the classical simulability with stabilizer states. In this work, we propose a…
