Stochastic correction to the Maxwell-Bloch equations via the positive representation
Johannes Stowasser, Felix Hitzelhammer, Michael A. Schreiber +4
Focusing on two-level atoms, we apply the positive representation to a full-wave mixed bosonic and fermionic system of Jaynes-Cummings type and identify an advantageous degree…

Multiphysics Numerical Method for Modeling Josephson Traveling-Wave Parametric Amplifiers
Samuel T. Elkin, Michael Haider, Thomas E. Roth
Josephson traveling-wave parametric amplifiers (JTWPAs) are wideband, ultralow-noise amplifiers used to enable the readout of superconducting qubits. While individual JTWPAs have a…
