Quantum Loads and the Generalized Telegrapher's Problem
E. Collin, A. Delattre
We report on the mapping of classical microwave transmission line theory onto the quantum scattering matrix description. By means of a generalized flux formalism a la Devoret, we d…
Canonical Quantization of Cylindrical Waveguides: A Gauge-Based Approach
Alexandre Delattre, Eddy Collin
We present a canonical quantization of electromagnetic modes in cylindrical waveguides, extending a gauge-based formalism previously developed for Cartesian geometries [1]. By intr…
Waveguides in a quantum perspective
Eddy Collin, Alexandre Delattre
Solid state quantum devices, operated at dilution cryostat temperatures, are relying on microwave signals to both drive and read-out their quantum states. These signals are transmi…
Quantitative calibration of a TWPA applied to an optomechanical platform
Alexandre Delattre, Ilya Golokolenov, Richard Pedurand +11
In the last decade, the microwave quantum electronics toolbox has been enriched with quantum-limited detection devices such as Traveling Wave Parametric Amplifiers (TWPAs). The ext…
