Entanglement Detection by Approximate Entanglement Witnesses
Samuel Dai, Ning Bao
The problem of determining whether a given quantum state is separable is known to be computationally difficult. We develop an approach to this problem based on approximations of co…

Optimal Locality and Parameter Tradeoffs for Subsystem Codes
Samuel Dai, Ray Li, Eugene Tang
We study the tradeoffs between the locality and parameters of subsystem codes. We prove lower bounds on both the number and lengths of interactions in any -dimensional embedding…
