Machine Learning Decoding of Circuit-Level Noise for Bivariate Bicycle Codes
John Blue, Harshil Avlani, Zhiyang He +2
Fault-tolerant quantum computers will depend crucially on the performance of the classical decoding algorithm which takes in the results of measurements and outputs corrections to…
Full Extractors for Logical Processing in Hypergraph Product Codes
John Blue, Zhiyang He, Hengyun Zhou +1
Quantum low-density parity-check (QLDPC) codes are promising candidates for practical low-overhead quantum memories. For large-scale fault-tolerant quantum computation, we further…
Parallel Logical Measurements via Quantum Code Surgery
Alexander Cowtan, Zhiyang He, Dominic J. Williamson +1
Quantum code surgery is a flexible and low overhead technique for performing logical measurements on quantum error-correcting codes, which generalises lattice surgery. In this work…
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…
Extractors: QLDPC Architectures for Efficient Pauli-Based Computation
Zhiyang He, Alexander Cowtan, Dominic J. Williamson +1
In pursuit of large-scale fault-tolerant quantum computation, quantum low-density parity-check (LDPC) codes have been established as promising candidates for low-overhead memory wh…
Quantum Codes with Addressable and Transversal Non-Clifford Gates
Zhiyang He, Vinod Vaikuntanathan, Adam Wills +1
The development of quantum codes with good error correction parameters and useful sets of transversal gates is a problem of major interest in quantum error-correction. Abundant pri…
