Ab initio extended Hubbard model of short polyenes for efficient quantum computing
Yuichiro Yoshida, Nayuta Takemori, Wataru Mizukami
We propose introducing an extended Hubbard Hamiltonian derived via the ab initio downfolding method, which was originally formulated for periodic materials, towards efficient quant…
Balancing error budget for fermionic k-RDM estimation
Nayuta Takemori, Yusuke Teranishi, Wataru Mizukami +1
The reduced density matrix (RDM) is crucial in quantum many-body systems for understanding physical properties, including all local physical quantity information. This study aims t…
A comprehensive survey on quantum computer usage: How many qubits are employed for what purposes?
Tsubasa Ichikawa, Hideaki Hakoshima, Koji Inui +18
Quantum computers (QCs), which work based on the law of quantum mechanics, are expected to be faster than classical computers in several computational tasks such as prime factoring…
