Exact Quantum Algorithms for Quantum Phase Recognition: Renormalization Group and Error Correction
Ethan Lake, Shankar Balasubramanian, Soonwon Choi
We explore the relationship between renormalization group (RG) flow and error correction by constructing quantum algorithms that exactly recognize 1D symmetry-protected topological…
Floquet codes without parent subsystem codes
Margarita Davydova, Nathanan Tantivasadakarn, Shankar Balasubramanian
We propose a new class of error-correcting dynamic codes in two and three dimensions that has no explicit connection to any parent subsystem code. The two-dimensional code, which w…
Interplay of symmetry breaking and deconfinement in 3D quantum vertex models
Shankar Balasubramanian, Daniel Bulmash, Victor Galitski +1
We construct a broad class of frustration-free quantum vertex models in 3+1D whose ground states are weighted superpositions of classical 3D vertex model configurations. Our result…
