Thermodynamic Limit in the Two-qubit Quantum Rabi Model with Spin-Spin Coupling
R. Grimaudo, G. Falci, A. Messina +4
The occurrence of a second-order superradiant quantum phase transition is brought to light in a quantum system consisting of two interacting qubits coupled to the same quantized fi…
Integrated conversion and photodetection of virtual photons in an ultrastrongly coupled superconducting quantum circuit
Luigi Giannelli, Giorgio Anfuso, Miroslav Grajcar +3
The ground-state of an artificial atom ultrastrongly coupled to quantized modes is entangled and contains an arbitrary number of virtual photons. The problem of their detection has…
Second spectrum of charge carrier density fluctuations in graphene due to trapping/detrapping processes
Francesco M. D. Pellegrino, Giuseppe Falci, Elisabetta Paladino
We investigate the second spectrum of charge carrier density fluctuations in graphene within the McWorther model, where noise is induced by electron traps in the substrate. Within…
Detecting virtual photons in ultrastrongly coupled superconducting quantum circuits
Luigi Giannelli, Elisabetta Paladino, Miroslav Grajcar +2
Light-matter interaction and understanding the fundamental physics behind is essential for emerging quantum technologies. Solid-state devices may explore new regimes where coupling…
Coarse-grained effective Hamiltonian via the Magnus Expansion for a three-level system
Nicola Macrì, Luigi Giannelli, Elisabetta Paladino +1
Quantum state processing is one of the main tools of quantum technologies. While real systems are complicated and/or may be driven by non-ideal control they may nevertheless exhibi…
