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…
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…
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…
Absence of a dissipative quantum phase transition in Josephson junctions
Anil Murani, Nicolas Bourlet, Hélène le Sueur +7
Half a century after its discovery, the Josephson junction has become the most important nonlinear quantum electronic component at our disposal. It has helped reshape the SI system…
Microscopic charged fluctuators as a limit to the coherence of disordered superconductor devices
Hélène le Sueur, Artis Svilans, Nicolas Bourlet +4
By performing experiments with thin-film resonators of NbSi, we elucidate a decoherence mechanism at work in disordered superconductors. This decoherence is caused by charged Two L…
Ion irradiated YBa2Cu3O7 nano-meanders for superconducting single photon detectors
P. Amari, C. Feuillet-Palma, A. Jouan +8
We report the fabrication of few hundred microns long, hundreds of nanometers wide and 30 nm thick meanders made from YBa2CU3O7. Thin films protected by a 8 nm-thick Ce02 cap layer…
