Dissipative Effects in Transmission Line Analogues of Hawking Radiation
Elián Urtubey, Fernando C. Lombardo, Paula I. Villar
Hawking radiation is a fundamental result of quantum field theory in curved spacetime, yet its direct observation remains beyond current experimental capabilities. Circuit quantum…
Dynamically Enabled Robustness of Geometric Phases and Entanglement in the Nonlinear Jaynes-Cummings Model
Ali Martin Zynda, Paula I. Villar, Fernando C. Lombardo
Robustness in dissipative light-matter systems has recently been associated with resonance conditions or geodesic evolution. We show that, in the nonlinear Jaynes-Cummings model, t…
Ergotropy from Geometric Phases in a Dephasing Qubit
Fernando C. Lombardo, Paula I. Villar
We analyze the geometric phase and dynamic phase acquired by a qubit coupled to an environment through pure dephasing, establishing a direct connection between phase accumulation a…
Geometric phase in dissipative quantum batteries
Camila Cristiano, Ludmila Viotti, Paula I. Villar
We study the geometric phase accumulated during non-adiabatic charging of different driven open quantum systems serving as quantum battery models. We provide a full numerical analy…
Dynamical Casimir effect in superconducting cavities: from photon generation to universal quantum gates
Fernando C. Lombardo, Paula I. Villar
This chapter explores various aspects of the Dynamical Casimir Effect (DCE) and its implications in the context of circuit quantum electrodynamics (cQED). We begin by reviewing the…
Controlled-squeeze gate in superconducting quantum circuits
Nicolás F. Del Grosso, Rodrigo G. Cortiñas, Paula I. Villar +2
We present a method to prepare non-classical states of the electromagnetic field in a microwave resonator. It is based on a controlled gate that applies a squeezing operation on a…
