High-rate qLDPC processors
Aditya Bhardwaj, Muzhou Ma, Nadine Meister +6
Despite significant progress on quantum low-density parity-check (qLDPC) codes, building qLDPC processors that are high-rate, high-throughput, hardware-friendly, and fast-to-decode…
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…
Shor's algorithm is possible with as few as 10,000 reconfigurable atomic qubits
Madelyn Cain, Qian Xu, Robbie King +6
Quantum computers have the potential to perform computational tasks beyond the reach of classical machines. A prominent example is Shor's algorithm for integer factorization and di…
Error-structure-tailored early fault-tolerant quantum computing
Pei Zeng, Guo Zheng, Qian Xu +1
Fault tolerance is widely regarded as indispensable for achieving scalable and reliable quantum computing. However, the spacetime overhead required for fault-tolerant quantum compu…
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…
