Universal Properties of Critical Mixed States from Measurement and Feedback
Zhehao Zhang, Yijian Zou, Timothy H. Hsieh +1
We explore the universal properties of mixed quantum matter obtained from "single-shot" adaptive evolution, in which a quantum-critical ground-state is manipulated through a single…

Quantum Communication and Mixed-State Order in Decohered Symmetry-Protected Topological States
Zhehao Zhang, Utkarsh Agrawal, Sagar Vijay
Certain pure-state symmetry-protected topological orders (SPT) can be used as a resource for transmitting quantum information. Here, we investigate the ability to transmit quantum…
