Theory and Architecture of Syndrome-Resolved Logical Gates

Nobuyuki Yoshioka, Alireza Seif, Peter Groszkowski +2

We introduce a general framework for weak transversal gates, namely syndrome-resolved implementation of logical unitaries realized by local physical unitaries, and demonstrate its…

Evolutionary Discovery of Bivariate Bicycle Codes with LLM-Guided Search

Juan Cruz-Benito, Andrew W. Cross, David Kremer +1

Quantum LDPC code discovery requires searching large algebraic design spaces while reliably certifying the parameters and equivalence classes of any candidates found. We introduce…

Improved QLDPC Surgery: Logical Measurements and Bridging Codes

Andrew W. Cross, Zhiyang He, Patrick J. Rall +1

In this paper, we introduce the gauge-fixed QLDPC surgery scheme, an improved logical measurement scheme based on the construction of Cohen et al. (Sci. Adv. 8, eabn1717). Our sche…

Non-Clifford and parallelizable fault-tolerant logical gates on constant and almost-constant rate homological quantum LDPC codes via higher symmetries

Guanyu Zhu, Shehryar Sikander, Elia Portnoy +2

We study parallel fault-tolerant quantum computing for families of homological quantum low-density parity-check (LDPC) codes defined on 3-manifolds with constant or almost-constant…

Tour de gross: A modular quantum computer based on bivariate bicycle codes

Theodore J. Yoder, Eddie Schoute, Patrick Rall +5

We present the bicycle architecture, a modular quantum computing framework based on high-rate, low-overhead quantum LDPC codes identified in prior work. For two specific bivariate…

Small Binary Stabilizer Subsystem Codes

Andrew Cross, Drew Vandeth

We establish a database consisting of a representative of every binary quantum stabilizer code under local Clifford permutation equivalence for .
