Variational Multi-Gaussian Phase-Space Dynamics via Automatic Differentiation
Jacopo Tosca, Francesco Carnazza, Luca Giacomelli +1
The paper presents a variational multi-Gaussian approach for simulating the dynamics of interacting open quantum bosonic systems, using a Wigner phase-space representation and auto…

Exact Duality at Low Energy in a Josephson Tunnel Junction Coupled to a Transmission Line
Luca Giacomelli, Michel H. Devoret, Cristiano Ciuti
We theoretically explore the low-energy behavior of a Josephson tunnel junction coupled to a finite-length, charge-biased transmission line and compare it to its flux-biased counte…
