Redesigning the linear--quadratic--Gaussian cost function for feedback cooling of a quantum harmonic oscillator
Shuma Sugiura, Koki Shiraishi, Masahito Ueda
Linear--quadratic--Gaussian (LQG) control is optimal only with respect to a prescribed cost function, the choice of which dictates the physical objective of the control. We conside…
Davies equation without the secular approximation: Reconciling locality with quantum thermodynamics for open quadratic systems
Koki Shiraishi, Masaya Nakagawa, Takashi Mori
We derive a thermodynamically consistent quantum master equation that satisfies locality for quadratic systems coupled to independent and identical baths at each site. We show that…
Quantum master equation for many-body systems: Derivation based on the Lieb-Robinson bound
Koki Shiraishi, Masaya Nakagawa, Takashi Mori +1
The local Gorini-Kossakowski-Sudarshan-Lindblad (GKSL) quantum master equation is a powerful tool for the study of open quantum many-body systems. However, its microscopic derivati…
