Error-Adaptive Quasi-local Decoding of the Toric Code
Hossein Dehghani, Sarang Gopalakrishnan, Michael Gullans
Topological quantum memories need decoders that are both reliable and scalable, but these goals compete: globally informed decoders are accurate near threshold yet expensive, while…
Anomalous Boundary Modes in a Floquet Hyperbolic System
Ali Fahimniya, Hossein Dehghani, Alicia J. Kollár +1
We construct an anomalous Floquet topological phase on a negatively curved hyperbolic lattice. The model is a tight-binding Hamiltonian with a periodically repeated four-color edge…
Generalized matching decoders for 2D topological translationally-invariant codes
Shi Jie Samuel Tan, Ian Gill, Eric Huang +6
Two-dimensional topological translationally-invariant (TTI) quantum codes, such as the toric code (TC) and bivariate bicycle (BB) codes, are promising candidates for fault-tolerant…
Estimation of Hamiltonian parameters from thermal states
Luis Pedro García-Pintos, Kishor Bharti, Jacob Bringewatt +4
We upper- and lower-bound the optimal precision with which one can estimate an unknown Hamiltonian parameter via measurements of Gibbs thermal states with a known temperature. The…
Fault-tolerant hyperbolic Floquet quantum error correcting codes
Ali Fahimniya, Hossein Dehghani, Kishor Bharti +4
A central goal in quantum error correction is to reduce the overhead of fault-tolerant quantum computing by increasing noise thresholds and reducing the number of physical qubits r…
