Is a single photon's wave front observable?
A. M. Zagoskin, R. D. Wilson, M. Everitt +5
The ultimate goal and the theoretical limit of weak signal detection is the ability to detect a single photon against a noisy background. [...] In this paper we show, that a combin…
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…
Frequency Division Multiplexing Readout and Simultaneous Manipulation of an Array of Flux Qubits
Markus Jerger, Stefano Poletto, Pascal Macha +3
An important desired ingredient of superconducting quantum circuits is a readout scheme whose complexity does not increase with the number of qubits involved in the measurement. He…
Heat cost of parametric generation of microwave squeezed states
A. M. Zagoskin, E. Il'ichev, Franco Nori
In parametric systems, squeezed states of radiation can be generated via extra work done by external sources. This eventually increases the entropy of the system despite the fact t…
