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…

Quantum-Computer-Based Verification of Quantum Thermodynamic Uncertainty Relation
Nobumasa Ishida, Yoshihiko Hasegawa
Quantum thermodynamic uncertainty relations establish fundamental trade-offs between the precision achievable in quantum systems and associated thermodynamic quantities such as ent…
