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…
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…
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…
Spin backflow: a non-Markovian effect on spin pumping
Kazunari Hashimoto, Gen Tatara, Chikako Uchiyama
The miniaturization of spintronic devices, specifically, nanoscale devices employing spintronics, has attracted intensive attention from a scientific as well as engineering perspec…
Nonadiabaticity in spin pumping under relaxation
Kazunari Hashimoto, Gen Tatara, Chikako Uchiyama
Using a minimum model consisting of a magnetic quantum dot and an electron lead, we investigate spin pumping by its precessing magnetization. Focusing on the "adiabaticity", which…
