Microwave photon-number amplification
Romain Albert, Joël Griesmar, Florian Blanchet +3
So far, quantum-limited power meters are not available in the microwave domain, hindering measurement of photon number in itinerant quantum states. On the one hand, single photon d…
Absorptive filters for quantum circuits: Efficient fabrication and cryogenic power handling
Alexandre Paquette, Joël Griesmar, Gabriel Lavoie +5
We present an efficient fabrication method for absorptive microwave filters based on Eccosorb CR-124. Filters are fabricated from readily available parts and their cut-off frequenc…
Generating two continuous entangled microwave beams using a dc-biased Josephson junction
A. Peugeot, G. Ménard, S. Dambach +14
We show experimentally that a dc-biased Josephson junction in series with two microwave resonators emits entangled beams of microwaves leaking out of the resonators. In the absence…
Microwave response and electrical transport studies of disordered s wave superconductor: NbN thin films
D. Hazra, S. Jebari, R. Albert +4
It is now well known that the properties of the disordered s wave superconductors can deviate significantly from the prediction of standard Bardeen-Cooper-Schrieffer (BCS) theory.…
A bright on-demand source of anti-bunched microwave photons based on inelastic Cooper pair tunneling
Alexander Grimm, Florian Blanchet, Romain Albert +8
The ability to generate single photons is not only an ubiquitous tool for scientific exploration with applications ranging from spectroscopy and metrology to quantum computing, but…
The role of Coulomb interaction in superconducting NbTiN thin films
D. Hazra, N. Tsavdaris, A. Mukhtarova +9
We report on the superconducting properties of NbTiN thin films of thickness 10 nm, with different Ti fraction in the range , deposited b…
