Coupled-Layer Codes: Beyond Quantum Product Constructions
Shuyu Zhang, Tzu-Chieh Wei, Nathanan Tantivasadakarn
Product codes are an important class of quantum error-correcting codes constructed from multiple input codes, which can give rise to asymptotically good quantum low-density parity…

Coupled-Layer Construction of Quantum Product Codes
Shuyu Zhang, Tzu-Chieh Wei, Nathanan Tantivasadakarn
Product codes are a class of quantum error correcting codes built from two or more constituent codes. They have recently gained prominence for a breakthrough yielding quantum low-d…

Local symmetries and extensive ground-state degeneracy of a 1D supersymmetric fermionic chain
Shuyu Zhang, Hiroki Sukeno, Kazuki Ikeda +1
We study a D supersymmetric (SUSY) hard-core fermion model first proposed by Fendley, Schoutens, and de Boer [Phys. Rev. Lett. 90, 120402 (2003)]. We focus on the full Hilbert s…
