Theory of nonequilibrium open quantum systems

  • 2.1 Quantum bits, memories, devices(Superconducting circuits, Ion trapping, Trapped cold atoms, Photons, Quantum dots, etc.)
  • 2.3 Quantum materials(Topological materials/Thermoelectric devices/Functional materials)

Quantum functional devices operate under out-of-equilibrium conditions and are necessarily open to external systems to be amenable to feedback control.
We develop fundamental theory to describe such devices on the basis of many-body theory, information thermodynamics, and machine learning.
Quantum systems subject to measurement and feedback are described as nonequilibrium open quantum systems.
