Zipping many-body quantum states: a scalable approach to diagonal entropy
Yu-Hsueh Chen, Tarun Grover
The outcomes of projective measurements on a quantum many-body system in a chosen basis are inherently probabilistic. The Shannon entropy of this probability distribution (the "dia…

Symmetry-enforced many-body separability transitions
Yu-Hsueh Chen, Tarun Grover
We study quantum many-body mixed states with a symmetry from the perspective of separability, i.e., whether a mixed state can be expressed as an ensemble of short-range entangled (…

Separability transitions in topological states induced by local decoherence
Yu-Hsueh Chen, Tarun Grover
We study states with intrinsic topological order subjected to local decoherence from the perspective of separability, i.e., whether a decohered mixed state can be expressed as an e…
