Bridging Quantum Noise and Classical Electrodynamics with Stochastic Methods
Felix Hitzelhammer, Johannes Stowasser, Lukas Hanschke +7
The development of emerging technologies in quantum optics demands accurate models that faithfully capture genuine quantum effects. Mature semiclassical approaches reach their limi…
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…
Modeling of Fluctuations in Dynamical Optoelectronic Device Simulations within a Maxwell-Density Matrix Langevin Approach
Johannes Popp, Johannes Stowasser, Michael A. Schreiber +5
We present a full-wave Maxwell-density matrix simulation tool including c-number stochastic noise terms for the modeling of the spatiotemporal dynamics in active photonic devices,…
