Logical computation with canonical lifted product codes
Han Zheng, Guo Zheng, Liang Jiang +1
The paper designs a logical instruction set for canonical lifted‑product quantum LDPC codes, enabling low‑overhead, fault‑tolerant operations such as transversal Clifford gates, mo…
Constant-Overhead Fault-Tolerant Bell-Pair Distillation using High-Rate Codes
J. Pablo Bonilla Ataides, Hengyun Zhou, Qian Xu +4
We present a fault-tolerant Bell-pair distillation scheme achieving constant overhead through high-rate quantum low-density parity-check (qLDPC) codes. Our approach maintains a con…
High-Rate Surgery: towards constant-overhead logical operations
Guo Zheng, Liang Jiang, Qian Xu
Scalable quantum computation requires not only quantum codes with low memory overhead but also encoded operations with low space-time overhead. High rate quantum low-density parity…
Achievable rates for concatenated square Gottesman-Kitaev-Preskill codes
Mahadevan Subramanian, Guo Zheng, Liang Jiang
The Gottesman-Kitaev-Preskill (GKP) codes are known to achieve optimal rates under displacement noise and pure loss channels, which establishes theoretical foundations for its opti…
Fast and Parallelizable Logical Computation with Homological Product Codes
Qian Xu, Hengyun Zhou, Guo Zheng +4
Quantum error correction is necessary to perform large-scale quantum computation, but requires extremely large overheads in both space and time. High-rate quantum low-density-parit…
