A superconducting qubit as a quantum transformer routing entanglement between a microscopic quantum memory and a macroscopic resonator
Alexander Kemp, Shiro Saito, William J. Munro +2
We demonstrate experimentally the creation and measurement of an entangled state between a microscopic two level system and a macroscopic superconducting resonator where their indi…
Coherent Operation of a Gap-tunable Flux Qubit
Xiaobo Zhu, Alexander Kemp, Shiro Saito +1
We replace the Josephson junction defining a three-junction flux qubit's properties with a tunable direct current superconducting quantum interference devices (DC-SQUID) in order t…
Vortex qubit based on an annular Josephson junction containing a microshort
A. N. Price, A. Kemp, D. R. Gulevich +2
We report theoretical and experimental work on the development of a vortex qubit based on a microshort in an annular Josephson junction. The microshort creates a potential barrier…
Ratchet-like dynamics of fluxons in annular Josephson junctions driven by bi-harmonic microwave fields
A. V. Ustinov, C. Coqui, A. Kemp +2
Experimental observation of the unidirectional motion of a topological soliton driven by a bi-harmonic ac force of zero mean is reported. The observation is made by measuring the c…
