Quantum Thermodynamics applied for Quantum Refrigerators cooling down a qubit
Hideaki Okane, Shunsuke Kamimura, Shingo Kukita +2
We discuss a quantum refrigerator to increase the ground state probability of a target qubit whose energy difference between the ground and excited states is less than the thermal…
Universal Scaling Bounds on a Quantum Heat Current
Shunsuke Kamimura, Kyo Yoshida, Yasuhiro Tokura +1
We derive new bounds on a heat current flowing into a quantum -particle system coupled with a Markovian environment. By assuming that a system Hamiltonian and a system-environme…
Quantum battery based on superabsorption
Yudai Ueki, Shunsuke Kamimura, Yuichiro Matsuzaki +2
A quantum battery is a device where an energy is charged by using a quantum effect. Here, we propose a quantum battery with a charger system composed of qubits by utilizing a c…
