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…

Quantum and Classical Potts Criticality in Driven-Dissipative Bosonic Lattices

Jacopo Tosca, Zejian Li, Cristiano Ciuti

The emergence of equilibrium universality from intrinsically nonequilibrium dynamics is a fundamental open problem. Bose-Hubbard lattices realized in photonic and circuit-QED platf…

Ising selector machine by Kerr parametric oscillators

Jacopo Tosca, Cristiano Ciuti, Claudio Conti +1

Ising machines are physical platforms designed to minimize the energy of classical Ising Hamiltonians, yet accessing specific excited states remains an open challenge of both funda…

Variational Dynamics of Open Quantum Spin Systems in Phase Space

Jacopo Tosca, Zejian Li, Francesco Carnazza +1

We introduce a variational method for simulating the dynamics of interacting open quantum spin systems. The method is based on the spin phase-space representation and variationally…

Emergent Equilibrium in All-Optical Single Quantum-Trajectory Ising Machines

Jacopo Tosca, Marcello Calvanese Strinati, Claudio Conti +1

We investigate the dynamics of multi-mode optical systems driven by two-photon processes and subject to non-local losses, incorporating quantum noise at the Gaussian level. Our fin…
