Information dynamics and symmetry breaking in generic monitored -symmetric open quantum systems
Jacob Hauser, Ali Lavasani, Sagar Vijay +1
We investigate the steady-state phases of generic -symmetric monitored, open quantum dynamics. We describe the phases systematically in terms of both information-theo…
Persistent Topological Negativity in a High-Temperature Mixed-State
Yonna Kim, Ali Lavasani, Sagar Vijay
We study the entanglement structure of the Greenberger-Horne-Zeilinger (GHZ) state as it thermalizes under a strongly-symmetric quantum channel describing the Metropolis-Hastings d…
On stability of k-local quantum phases of matter
Ali Lavasani, Michael J. Gullans, Victor V. Albert +1
The current theoretical framework for topological phases of matter is based on the thermodynamic limit of a system with geometrically local interactions. A natural question is to w…
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…
