Quantum memory at nonzero temperature in a thermodynamically trivial system
Yifan Hong, Jinkang Guo, Andrew Lucas
Passive error correction protects logical information forever in the thermodynamic limit by updating the system based only on local information and few-body interactions. A paradig…

Towards self-correcting quantum codes for neutral atom arrays
Jinkang Guo, Yifan Hong, Adam Kaufman +1
Discovering low-overhead quantum error-correcting codes is of significant interest for fault-tolerant quantum computation. For hardware capable of long-range connectivity, the biva…

Designing open quantum systems with known steady states: Davies generators and beyond
Jinkang Guo, Oliver Hart, Chi-Fang Chen +2
We provide a systematic framework for constructing generic models of nonequilibrium quantum dynamics with a target stationary (mixed) state. Our framework identifies (almost) all c…
