Thermodynamic uncertainty relation for generalized time-reversal observables

Tetta Indo, Yoshihiko Hasegawa

Time-reversal symmetry plays an essential role in the thermodynamic uncertainty relations, which bound the fluctuations of observables in terms of the associated dissipation. In fa…

Thermodynamic Recycling of Algorithmic Failure Branches: Quantum-Computer Demonstration with Quantum Error Correction

Nobumasa Ishida, Yoshihiko Hasegawa

Thermodynamic trade-off relations dictate fundamental limits on the performance of thermodynamic tasks through costs such as heat dissipation. Here, we propose a framework called t…

Optimal Control to Minimize Dissipation and Fluctuations in Open Quantum Systems Beyond Slow and Rapid Regimes

Yuki Kurokawa, Yoshihiko Hasegawa

Optimal control is a central problem in quantum thermodynamics. When minimizing dissipated work and work fluctuations defined via the two-point measurement scheme in open quantum s…

Entropic trade-off relations in stochastic thermodynamics via replica Markov processes

Yoshihiko Hasegawa

Traditional thermodynamic trade-off relations usually apply to quantities that depend linearly on probability distributions. In contrast, many important information-theoretic measu…

Sparse QUBO Formulation for Efficient Embedding via Network-Based Decomposition of Equality and Inequality Constraints

Kohei Suda, Soshun Naito, Yoshihiko Hasegawa

Quantum annealing is a promising approach for solving combinatorial optimization problems. However, its performance is often limited by the overhead of additional qubits required f…

Unified quantification of entanglement and magic in information scrambling and their trade-off relation

Mao Kaneyasu, Yoshihiko Hasegawa

Entanglement and magic are among the most fundamental properties unique to quantum systems. Each quantity captures a different aspect of non-classical behavior, and each can be reg…
