Dressed-state amplification by a superconducting qubit
G. Oelsner, P. Macha, O. V. Astafiev +6
We demonstrate amplification of a microwave signal by a strongly driven two-level system in a coplanar waveguide resonator. The effect known from optics as dressed-state lasing is…

Coherent quantum phase slip
O. V. Astafiev, L. B. Ioffe, S. Kafanov +5
A hundred years after discovery of superconductivity, one fundamental prediction of the theory, the coherent quantum phase slip (CQPS), has not been observed. CQPS is a phenomenon…
