Emission of non-classical radiation by inelastic Cooper pair tunneling
M. Westig, B. Kubala, O. Parlavecchio +11
We show that a properly dc-biased Josephson junction in series with two microwave resonators of different frequencies emits photon pairs in the resonators. By measuring auto- and i…
Fluctuation-Dissipation Relations of a Tunnel Junction Driven by a Quantum Circuit
O. Parlavecchio, C. Altimiras, J. -R. Souquet +7
We derive fluctuation-dissipation relations for a tunnel junction driven by a high impedance microwave resonator, displaying strong quantum fluctuations. We find that the fluctuati…
Tunable microwave impedance matching to a high impedance source using a Josephson metamaterial
Carles Altimiras, Olivier Parlavecchio, Philippe Joyez +4
We report the efficient coupling of a microwave circuit to a high impedance conductor. We use an impedance transformer consisting of a co-planar resonator whose inner…
Dynamical Coulomb Blockade of Shot Noise
C. Altimiras, O. Parlavecchio, P. Joyez +4
We observe the suppression of the finite frequency shot-noise produced by a voltage biased tunnel junction due to its interaction with a single electromagnetic mode of high impedan…
