Arbitrary-Distance Quantum Error Correction with Gauss's Law for Lattice Gauge Theory
Neel S. Modi, Lento Nagano, Masazumi Honda +2
It has previously been shown by Rajput, Roggero, and Wiebe that Gauss's law constraints can be used to build efficient quantum error-correcting codes (QECCs) that are…
Theory and Architecture of Syndrome-Resolved Logical Gates
Nobuyuki Yoshioka, Alireza Seif, Peter Groszkowski +2
We introduce a general framework for weak transversal gates, namely syndrome-resolved implementation of logical unitaries realized by local physical unitaries, and demonstrate its…
Quantum advantages for syndrome-aware noisy logical observable estimation
Kento Tsubouchi, Hyukgun Kwon, Liang Jiang +1
Recent progress in fault-tolerant quantum computing suggests that leveraging error-syndrome information at the logical layer can substantially improve performance, including the es…
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…
Robust Error Accumulation Suppression for Quantum Circuits
Tatsuki Odake, Philip Taranto, Nobuyuki Yoshioka +4
We present a \textit{robust error accumulation suppression} (\textbf{REAS}) technique to manage errors in quantum computers. Our method reduces the accumulation of errors in any qu…
