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…
