Phase-stable voltage bias for Josephson photonics devices
Amir Hosein Esmaeili, Naveen Nehra, Alexandre Paquette +8
Parametric interactions are foundational to superconducting quantum technologies, yet conventional microwave-driven pumping introduces parasitic Kerr nonlinearities and higher-orde…
Stroboscopic detection of itinerant microwave photons
Hanna Zeller, Lukas Danner, Max Hofheinz +3
We present a novel scheme to detect itinerant microwave radiation at the single photon level. Using existing Josephson-photonics devices, where two microwave cavities are coupled b…
DC-powered broadband quantum-limited microwave amplifier
N. Nehra, N. Bourlet, A. H. Esmaeili +7
Fast, high-fidelity, single-shot readout of superconducting qubits in quantum processors demands quantum-limited amplifiers to preserve the optimal signal-to-noise ratio. Typically…
Amplification and Detection of Single Itinerant Microwave Photons
Lukas Danner, Max Hofheinz, Nicolas Bourlet +3
Single-photon detectors are an essential part of the toolbox of modern quantum optics for implementing quantum technologies and enabling tests of fundamental physics. The low energ…
Influence of bias voltage noise on the Inelastic Cooper-Pair Tunneling Amplifier (ICTA)
Ulrich Martel, Romain Albert, Florian Blanchet +7
We experimentally show that the Inelastic Cooper-Pair Tunneling Amplifier (ICTA), implementing a DC-powered parametric amplification scheme, can achieve gain and noise performance…
Quantum limited amplification from inelastic Cooper pair tunneling
S. Jebari, F. Blanchet, A. Grimm +7
Nature sets fundamental limits regarding how accurate the amplification of analog signals may be. For instance, a linear amplifier unavoidably adds some noise which amounts to half…
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…
The Bright Side of Coulomb Blockade
Max Hofheinz, Fabien Portier, Quentin Baudouin +5
We explore the photonic (bright) side of dynamical Coulomb blockade (DCB) by measuring the radiation emitted by a dc voltage-biased Josephson junction embedded in a microwave reson…
