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…
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…
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…
The Stability of Gapped Quantum Matter and Error-Correction with Adiabatic Noise
Ali Lavasani, Sagar Vijay
The codespace of a quantum error-correcting code can often be identified with the degenerate ground-space within a gapped phase of quantum matter. We argue that the stability of su…
