Designer Codes from GALA: Compact, Self-Dual, and Rate-1/2 QEC on Reconfigurable Atom Arrays
Willers Yang, Casey Duckering, Arpit Dua
High rate quantum low-density parity-check codes on reconfigurable neutral-atom arrays can reduce the overhead of quantum error correction, but near-term devices support only hundr…
Clifford-deformed zero-rate LDPC codes with 50% biased noise thresholds
Jagannath Das, Sayandip Dhara, Pedro Medina +2
Applying single-qubit Clifford unitaries to a Pauli stabilizer code produces a Clifford-deformed variant whose stabilizers remain Pauli operators, but with locally rotated Pauli ax…
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…
A robust phase of continuous transversal gates in quantum stabilizer codes
Eric Huang, Pierre-Gabriel Rozon, Arpit Dua +2
A quantum error correcting code protects encoded logical information against errors. Transversal gates are a naturally fault-tolerant way to manipulate logical qubits but cannot be…
Fault-tolerant protocols through spacetime concatenation
Yichen Xu, Arpit Dua
We introduce a framework called spacetime concatenation for fault-tolerant compilation of syndrome extraction circuits of stabilizer codes. Spacetime concatenation enables efficien…
Subsystem Symmetry Fractionalization and Foliated Field Theory
Po-Shen Hsin, David T. Stephen, Arpit Dua +1
Topological quantum matter exhibits a range of exotic phenomena when enriched by subdimensional symmetries. This includes new features beyond those that appear in the conventional…
