Quantum Circuit Unoptimization
Yusei Mori, Hideaki Hakoshima, Kyohei Sudo +3
Optimization of circuits is an essential task for both quantum and classical computers to improve their efficiency. In contrast, classical logic optimization is known to be difficu…
Resource-efficient Generalized Quantum Subspace Expansion
Bo Yang, Nobuyuki Yoshioka, Hiroyuki Harada +5
Realizing practical quantum computing requires overcoming a number of computation errors and the limitation of device size, which have intensively been tackled by quantum error mit…
Localized Virtual Purification
Hideaki Hakoshima, Suguru Endo, Kaoru Yamamoto +2
Analog and digital quantum simulators can efficiently simulate quantum many-body systems that appear in natural phenomena. However, experimental limitations of near-term devices st…
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…
QAOA-MC: Markov chain Monte Carlo enhanced by Quantum Alternating Operator Ansatz
Yuichiro Nakano, Hideaki Hakoshima, Kosuke Mitarai +1
Quantum computation is expected to accelerate certain computational task over classical counterpart. Its most primitive advantage is its ability to sample from classically intracta…
