Quantum Routing and Entanglement Dynamics Through Bottlenecks
Dhruv Devulapalli, Chao Yin, Andrew Y. Guo +4
To implement arbitrary quantum circuits in architectures with restricted interactions, one may effectively simulate all-to-all connectivity by routing quantum information. We consi…

Lieb-Robinson bounds with exponential-in-volume tails
Ben T. McDonough, Chao Yin, Andrew Lucas +1
Lieb-Robinson bounds demonstrate the emergence of locality in many-body quantum systems. Intuitively, Lieb-Robinson bounds state that with local or exponentially decaying interacti…

Low-density parity-check codes as stable phases of quantum matter
Chao Yin, Andrew Lucas
Phases of matter with robust ground-state degeneracy, such as the quantum toric code, are known to be capable of robust quantum information storage. Here, we address the converse q…
