Single-shot readout of a superconducting flux qubit with a flux-driven Josephson parametric amplifier
Z. R. Lin, K. Inomata, W. D. Oliver +4
We report single-shot readout of a superconducting flux qubit by using a flux-driven Josephson parametric amplifier (JPA). After optimizing the readout power, gain of the JPA and t…
Sub-microsecond fast temporal evolution of the spin Seebeck effect
M. Agrawal, V. I. Vasyuchka, A. A. Serga +7
We present temporal evolution of the spin Seebeck effect in a YIG|Pt bilayer system. Our findings reveal that this effect is a sub-microseconds fast phenomenon governed by the temp…
Controllable microwave three-wave mixing via a single three-level superconducting quantum circuit
Yu-xi Liu, Hui-Chen Sun, Z. H. Peng +3
Three-wave mixing in second-order nonlinear optical processes cannot occur in atomic systems due to the electric-dipole selection rules. In contrast, we demonstrate that second-ord…
Squeezing with a flux-driven Josephson parametric amplifier
L. Zhong, E. P. Menzel, R. Di Candia +12
Josephson parametric amplifiers (JPA) are promising devices for applications in circuit quantum electrodynamics (QED) and for studies on propagating quantum microwaves because of t…
Observation of Longitudinal Spin Seebeck Effect with Various Transition Metal Films
M. Ishida, A. Kirihara, H. Someya +4
We evaluated the thermoelectric properties of longitudinal spin Seebeck devices by using ten different transition metals (TMs). Both the intensity and sign of spin Seebeck coeffici…
Context-based Barrier Notification Service Toward Outdoor Support for the Elderly
Keisuke Umezu, Takahiro Kawamura, Akihiko Ohsuga
Aging society has been becoming a global problem not only in advanced countries. Under such circumstances, it is said that participation of elderly people in social activities is h…
