Information dynamics in decohered quantum memory with repeated syndrome measurements: a dual approach
Jacob Hauser, Yimu Bao, Shengqi Sang +3
Measurements can detect errors in a decohered quantum memory allowing active error correction to increase the memory time. Previous understanding of this mechanism has focused on e…

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…
