Geometric blockade in a quantum dot coupled to two-dimensional and three dimensional electron gases
K. Yamada, M. Stopa, T. Hatano +4
We fabricated a quantum dot coupled laterally to a two-dimensional electron gas and vertically to a three-dimensional electron gas in order to investigate the eigenstate dependence…
Thermodynamics of Computation for CMOS NAND Gate
Daigo Yoshino, Yasuhiro Tokura
Understanding how much energy is needed and dissipated as heat for a given computational system and for a given program is a physically interesting and practically important proble…
Anonymous estimation of intensity distribution of magnetic fields with quantum sensing network
Hiroto Kasai, Yuki Takeuchi, Yuichiro Matsuzaki +1
A quantum sensing network is used to simultaneously detect and measure physical quantities, such as magnetic fields, at different locations. However, there is a risk that the measu…
Phonon-mediated spin dynamics in a two-electron double quantum dot under a phonon temperature gradient
Kazuyuki Kuroyama, Sadashige Matsuo, Seigo Tarucha +1
We have theoretically studied phonon-mediated spin-flip processes of electrons in a GaAs double quantum dot (DQD) holding two spins, under a phonon temperature gradient over the DQ…
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…
Heat transport through a two-level system under continuous quantum measurement
Tsuyoshi Yamamoto, Yasuhiro Tokura, Takeo Kato
We study the backaction of quantum measurements on heat transport through a two-level system by considering the continuous quantum measurement onto an eigenstate of the two-level s…
