Bias-preserving computation with the bit-flip code
Shoichiro Tsutsui, Keita Kanno
We explore the feasibility of fault-tolerant quantum computation using the bit-flip repetition code in a biased noise channel where only the bit-flip error can occur. While several…
Modal analysis on quantum computers via qubitization
Yasunori Lee, Keita Kanno
Natural frequencies and normal modes are basic properties of a structure which play important roles in analyses of its vibrational characteristics. As their computation reduces to…
Minimizing readout-induced noise for early fault-tolerant quantum computers
Yunzhe Zheng, Keita Kanno
Quantum error correcting code can diagnose potential errors and correct them based on measured outcomes by leveraging syndrome measurement. However, mid-circuit measurement has bee…
Computational analysis of chemical reactions using a variational quantum eigensolver algorithm without specifying spin multiplicity
Soichi Shirai, Hokuto Iwakiri, Keita Kanno +4
The analysis of a chemical reaction along the ground state potential energy surface in conjunction with an unknown spin state is challenging because electronic states must be separ…
Quantum-Selected Configuration Interaction: classical diagonalization of Hamiltonians in subspaces selected by quantum computers
Keita Kanno, Masaya Kohda, Ryosuke Imai +4
We propose quantum-selected configuration interaction (QSCI), a class of hybrid quantum-classical algorithms for calculating the ground- and excited-state energies of many-electron…
Almost optimal measurement scheduling of molecular Hamiltonian via finite projective plane
Wataru Inoue, Koki Aoyama, Yusuke Teranishi +3
We propose an efficient and almost optimal scheme for measuring molecular Hamiltonians in quantum chemistry on quantum computers, which requires distinct measurements in the…
