Monte Carlo Simulation of Operator Dynamics and Entanglement in Dual-Unitary Circuits
Menghan Song, Zhaoyi Zeng, Ting-Tung Wang +3
We investigate operator dynamics and entanglement growth in dual-unitary circuits, a class of locally scrambled quantum systems that enables efficient simulation beyond the exponen…

An analog of topological entanglement entropy for mixed states
Ting-Tung Wang, Menghan Song, Zi Yang Meng +1
We propose the convex-roof extension of quantum conditional mutual information ("co(QCMI)") as a diagnostic of topological order in a mixed state. We focus primarily on topological…
