Gate-Based Quantum Simulation of Finite-Temperature Open-System Dynamics: A Post-Processing Reconstruction Approach for Collision Models
Kazunari Hashimoto, Chikako Uchiyama
Simulating open-system dynamics on gate-based quantum computers offers a route to exploring dissipative quantum phenomena through programmable quantum processing. Collision models…
Dynamics of a quantum interacting system: Extended global approach beyond the Born-Markov and secular approximation
Chikako Uchiyama
In various fields from quantum physics to biology, the open quantum dynamics of a system consisting of interacting subsystems emphasizes its fundamental functionality. The local ap…
Theoretical bound of the efficiency of learning
Shanhe Su, Ousi Pan, Shihao Xia +2
A unified thermodynamic formalism describing the efficiency of learning is proposed. First, we derive an inequality, which is more strength than Clausius's inequality, revealing th…
Effect of quantum coherence on Landauer's principle
Kazunari Hashimoto, Chikako Uchiyama
Quantum Landauer's principle provides a fundamental lower bound for energy dissipation occurred with information erasure in the quantum regime. While most studies have related the…
Finite-time quantum measurement cooling beyond the Carnot limit
Tong Fu, Jianying Du, Jingyi Chen +3
We proposed the finite-time cycle model of a measurement-based quantum cooler, where invasive measurement provides the power to drive the cooling cycle. Such a cooler may be regard…
Lower bounds for the mean dissipated heat in an open quantum system
Kazunari Hashimoto, Bassano Vacchini, Chikako Uchiyama
Landauer's principle provides a perspective on the physical meaning of information as well as on the minimum working cost of information processing. Whereas most studies have relat…
