Thermal transport in nanoelectronic devices cooled by on-chip magnetic refrigeration
S. Autti, F. C. Bettsworth, K. Grigoras +8
On-chip demagnetization refrigeration has recently emerged as a powerful tool for reaching microkelvin electron temperatures in nanoscale structures. The relative importance of coo…
On the origin of the controversial electrostatic field effect in superconductors
Ilia Golokolenov, Andrew Guthrie, Sergey Kafanov +2
In semiconductor electronics, the field-effect refers to the control of electrical conductivity in nanoscale devices, which underpins the field-effect transistor, one of the corner…
Multiplexing Superconducting Qubit Circuit for Single Microwave Photon Generation
R E George, J Senior, O-P Saira +4
We report on a device that integrates eight superconducting transmon qubits in lambda/4 superconducting coplanar waveguide resonators fed from a common feedline. Using this multipl…
Coherent superconducting quantum pump
F. Hoehne, Yu. A. Pashkin, O. V. Astafiev +3
We demonstrate non-adiabatic charge pumping utilizing a sequence of coherent oscillations between a superconducting island and two reservoirs. Our method, based on pulsed quantum s…
Dynamics of coherent and incoherent emission from an artificial atom in a 1D space
A. A. Abdumalikov, O. V. Astafiev, Y. Nakamura +1
We study dynamics of an artificial two-level atom in an open 1D space by measuring evolution of its coherent and incoherent emission. States of the atom -- a superconducting flux q…
Photon assisted tunneling as an origin of the Dynes density of states
J. P. Pekola, V. F. Maisi, S. Kafanov +6
We show that the effect of a high-temperature environment in current transport through a normal metal-insulator-superconductor tunnel junction can be described by an effective dens…
Photon-induced entanglement of distant mesoscopic SQUID rings
A. Vourdas, D. I. Tsomokos, C. C. Chong
An experiment that involves two distant mesoscopic SQUID rings is studied. The superconducting rings are irradiated with correlated photons, which are produced by a single microwav…
Charge echo in a Cooper-pair box
Y. Nakamura, Yu. A. Pashkin, T. Yamamoto +1
A spin-echo-type technique is applied to an artificial two-level system that utilizes charge degree of freedom in a small superconducting electrode. Gate-voltage pulses are used to…
