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…
Diagonalization of large many-body Hamiltonians on a quantum processor
Nobuyuki Yoshioka, Mirko Amico, William Kirby +16
The estimation of low energies of many-body systems is a cornerstone of computational quantum sciences. Variational quantum algorithms can be used to prepare ground states on pre-f…
Error Crafting in Mixed Quantum Gate Synthesis
Nobuyuki Yoshioka, Seiseki Akibue, Hayata Morisaki +2
In fault-tolerant quantum computing, errors in unitary gate synthesis is comparable with noise inherent in the gates themselves. While mixed synthesis can suppress such coherent er…
Symmetric Clifford twirling for cost-optimal quantum error mitigation in early FTQC regime
Kento Tsubouchi, Yosuke Mitsuhashi, Kunal Sharma +1
Twirling noise affecting quantum gates is essential in understanding and controlling errors, but applicable operations to noise are usually restricted by symmetries inherent in qua…
