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…
Anomalously large spin-dependent electron correlation in nearly half-metallic ferromagnet CoS
Hirokazu Fujiwara, Kensei Terashima, Junya Otsuki +19
The spin-dependent band structure of CoS which is a candidate for a half-metallic ferromagnet was investigated by both spin- and angle-resolved photoemission spectroscopy and t…
Supercurrent Distribution in Real-Space and Anomalous Paramagnetic Response in a Superconducting Quasicrystal
Takumi Fukushima, Nayuta Takemori, Shiro Sakai +2
We theoretically study the real-space distribution of the supercurrent that flows under a uniform vector potential in a two-dimensional quasiperiodic structure. This is done by con…
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…
