A superconducting surface-code processor with lattice-surgery logical operations
Yanzhe Wang, Fanhao Shen, Haipeng Xie +31
Fault-tolerant logical operations are fundamental for scalable quantum computation. Here, we report the experimental realization of lattice-surgery operations between a pair of dis…
Simple, Efficient, and Generic Post-Selection Decoding for qLDPC codes
Haipeng Xie, Nobuyuki Yoshioka, Kento Tsubouchi +1
Quantum error correction is indispensable for scalable quantum computation. Although encoding logical qubits substantially enhances noise resilience, achieving logical error rates…
Noise-Agnostic Unbiased Quantum Error Mitigation for Logical Qubits
Haipeng Xie, Nobuyuki Yoshioka, Kento Tsubouchi +1
Probabilistic error cancellation is a quantum error mitigation technique capable of producing unbiased computation results but requires an accurate error model. Constructing this m…
Demonstrating quantum error mitigation on logical qubits
Aosai Zhang, Haipeng Xie, Yu Gao +32
A long-standing challenge in quantum computing is developing technologies to overcome the inevitable noise in qubits. To enable meaningful applications in the early stages of fault…
