Degeneracy Cutting: A Local and Efficient Post-Processing for Belief Propagation Decoding of Quantum Low-Density Parity-Check Codes
Kento Tsubouchi, Hayata Yamasaki, Shiro Tamiya
Quantum low-density parity-check (qLDPC) codes are promising for realizing scalable fault-tolerant quantum computation due to their potential for low-overhead protocols. A common a…
Hardness of classically sampling quantum chemistry circuits
Ayoub Hafid, Hokuto Iwakiri, Kento Tsubouchi +2
Significant advances have been made in the study of quantum advantage both in theory and experiment, although these have mostly been limited to artificial setups. In this work, we…
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…
Symmetric channel verification for purifying noisy quantum channels
Kento Tsubouchi, Yosuke Mitsuhashi, Ryuji Takagi +1
Symmetry inherent in quantum states has been widely used to reduce the effect of noise in quantum error correction and a quantum error mitigation technique known as symmetry verifi…
