Self-dual bivariate bicycle codes with transversal Clifford gates
Zijian Liang, Yu-An Chen
Bivariate bicycle codes are promising candidates for high-threshold, low-overhead fault-tolerant quantum memories. Meanwhile, color codes are the most prominent self-dual CSS codes…
Planar quantum low-density parity-check codes with open boundaries
Zijian Liang, Jens Niklas Eberhardt, Yu-An Chen
Although high-threshold and low-overhead quantum low-density parity-check (qLDPC) codes, such as bivariate bicycle (BB) codes, can reduce the physical-qubit cost by an order of mag…
Anyon Theory and Topological Frustration of High-Efficiency Quantum Low-Density Parity-Check Codes
Keyang Chen, Yuanting Liu, Yiming Zhang +4
Quantum low-density parity-check (QLDPC) codes offer a promising path to low-overhead fault-tolerant quantum computation but lack systematic strategies for exploration. In this Let…
Generalized toric codes on twisted tori for quantum error correction
Zijian Liang, Ke Liu, Hao Song +1
The Kitaev toric code is widely considered one of the leading candidates for error correction in fault-tolerant quantum computation. However, direct methods to increase its logical…
