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…

Locality vs Quantum Codes
Samuel Dai, Ray Li
This paper proves optimal tradeoffs between the locality and parameters of quantum error-correcting codes. Quantum codes give a promising avenue towards quantum fault tolerance, bu…
