Good Quantum Locally Testable Codes from Lossless Cubical Complexes
Itay Cohen, Itai Leigh, Assaf Reiner +2
Sipser and Spielman constructed LDPC codes from either bipartite \emph{spectral} expanders or one-sided \emph{lossless} expanders. In higher dimensions, \emph{spectral} expansion s…

Explicit Lossless Vertex Expanders
Jun-Ting Hsieh, Alexander Lubotzky, Sidhanth Mohanty +2
We give the first construction of explicit constant-degree lossless vertex expanders. Specifically, for any and sufficiently large , we give an explicit constr…
