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…
Averaging gate approximation error and performance of Unitary Coupled Cluster ansatz in Pre-FTQC Era
Kohdai Kuroiwa, Yuya O. Nakagawa
Fault-tolerant quantum computation (FTQC) is essential to implement quantum algorithms in a noise-resilient way, and thus to enjoy advantages of quantum computers even with presenc…
Density-Induced Hadron-Quark Crossover via the Formation of Cooper Triples
Hiroyuki Tajima, Shoichiro Tsutsui, Takahiro M. Doi +1
We discuss the hadron--quark crossover accompanied by the formation of Cooper triples (three-body counterpart of Cooper pairs) by analogy with the Bose--Einstein condensate to Bard…
Analytical formulation of the second-order derivative of energy for orbital-optimized variational quantum eigensolver: application to polarizability
Yuya O. Nakagawa, Jiabao Chen, Shotaro Sudo +2
We develop a quantum-classical hybrid algorithm to calculate the analytical second-order derivative of the energy for the orbital-optimized variational quantum eigensolver (OO-VQE)…
