Decohering Kitaev's Sixteenfold Way: A Holographic Approach
Shuyu Zhang, Linhao Li, Zhen Bi +2
We study anyon decoherence in 2D topological order, with the fermion decoherence in Kitaev's sixteenfold way as explicit examples. The sixteenfold way includes chiral topological p…
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…
Improved Quantum Power Method and Numerical Integration Using Quantum Singular Value Transformation
Nhat A. Nghiem, Hiroki Sukeno, Shuyu Zhang +1
Quantum singular value transformation (QSVT) is a framework that has been shown to unify many primitives in quantum algorithms. In this work, we leverage the QSVT framework in two…
Spontaneous symmetry breaking on surface defects
Gabriel Cuomo, Shuyu Zhang
Coleman's theorem states that continuous internal symmetries cannot be spontaneously broken in two-dimensional quantum field theories (QFTs). In this work we consider surface (i.e.…
