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…
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…
Non-Markovian effect on quantum Otto engine: -Role of system--reservoir interaction-
Yuji Shirai, Kazunari Hashimoto, Ryuta Tezuka +2
We study a limit cycle of a quantum Otto engine whose each cycle consists of two finite-time quantum isochoric (heating or cooling) processes and two quantum adiabatic work-extract…
