Search for galactic axions with a traveling wave parametric amplifier
R. Di Vora, A. Lombardi, A. Ortolan +24
A traveling wave parametric amplifier has been integrated in the haloscope of the QUAX experiment. A search for dark matter axions has been performed with a high Q dielectric cavit…
Investigating pump harmonics generation in a SNAIL-based Traveling Wave Parametric Amplifier
A. Yu. Levochkina, H. G. Ahmad, P. Mastrovito +16
Traveling Wave Parametric Amplifiers (TWPAs) are extensively employed in experiments involving weak microwave signals for their highly desirable quantum-limited and broadband chara…
Fast high fidelity quantum non-demolition qubit readout via a non-perturbative cross-Kerr coupling
R. Dassonneville, T. Ramos, V. Milchakov +12
Qubit readout is an indispensable element of any quantum information processor. In this work, we experimentally demonstrate a non-perturbative cross-Kerr coupling between a transmo…
Magnetic-field dependence of a Josephson traveling-wave parametric amplifier and integration into a high-field setup
L. M. Janssen, G. Butseraen, J. Krause +6
We investigate the effect of magnetic field on a photonic-crystal Josephson traveling-wave parametric amplifier (TWPA). We show that the observed change in photonic bandgap and pla…
Simulating MADMAX in 3D: Requirements for Dielectric Axion Haloscopes
S. Knirck, J. Schütte-Engel, S. Beurthey +38
We present 3D calculations for dielectric haloscopes such as the currently envisioned MADMAX experiment. For ideal systems with perfectly flat, parallel and isotropic dielectric di…
Transmon-qubit readout using in-situ bifurcation amplification in the mesoscopic regime
R. Dassonneville, T. Ramos, V. Milchakov +8
We demonstrate a transmon qubit readout based on the nonlinear response to a drive of polaritonic meters in-situ coupled to the qubit. Inside a 3D readout cavity, we place a transm…
