Anisotropic information geometry of entropy production
Tomohiro Nishiyama, Yoshihiko Hasegawa
We reveal that the information geometry of entropy production exhibits an intrinsic anisotropy, providing a unified origin for the inequivalent geometric constraints obeyed by its…
Heisenberg Scaling in Many-Body Kinetic Uncertainty Relation via Quantum Feedback
Hayato Yunoki, Yoshihiko Hasegawa
Precision is a central figure of merit for quantum devices, including quantum clocks whose performance is determined by the stability of counting events. Kinetic uncertainty relati…
Thermodynamics of classifiers
Yoshihiko Hasegawa
Reducing computational accuracy can lower energy consumption, and this principle is widely used to improve energy efficiency in computing. This raises a fundamental question: what…
Trade-off Relation for Black Hole Entropy Fluctuations
Kensuke Gallock-Yoshimura, Yoshihiko Hasegawa
Black holes respond to infalling quantum matter fields by changing their entropy. Since such matter is quantum in nature, the entropy response should be sensitive to its quantum fl…
Structural -divergence: Tight universal bounds for cost function moments and gradients in parameterized quantum circuits
Tomohiro Nishiyama, Yoshihiko Hasegawa
The barren plateau phenomenon, in which cost-function gradients of variational quantum algorithms vanish exponentially, remains a central obstacle for near-term quantum computing.…
Kinetic Uncertainty Relation in Collective Dissipative Quantum Many-Body Systems
Hayato Yunoki, Yoshihiko Hasegawa
Attaining the ultimate precision remains a central objective in the engineering of nanoscale systems and the investigation of nonequilibrium processes. While thermodynamic and kine…
