Efficient Quantum Algorithm for Solving Linear Distributed Delay Differential Equations
Wataru Setoyama, Keisuke Fujii
Non-Markovian dynamics is ubiquitous in both quantum and classical systems, but the numerical computation of the time-delay dynamics is demanding. In this work, we propose an effic…

Feedback-enhanced quantum reservoir computing with weak measurements
Tomoya Monomi, Wataru Setoyama, Yoshihiko Hasegawa
Quantum reservoir computing (QRC) leverages the natural dynamics of quantum systems to process time-series data efficiently, offering a promising approach for near-term quantum dev…

Lie algebraic quantum phase reduction based on heterodyne detection
Wataru Setoyama, Yoshihiko Hasegawa
Measurement backaction inherently alters observed dynamics in quantum physics. In the realm of quantum synchronization, this backaction induces a phase bias, making the assessment…
