Unveiling and veiling a Schrödinger cat state from the vacuum
Roberto Stassi, Mauro Cirio, Ken Funo +3
Deep in the ultrastrong light-matter coupling regime, it has been predicted that the ground state of a two-level atom interacting with a cavity mode takes the form of a "virtual" S…
Fast binomial-code holonomic quantum computation with ultrastrong light-matter coupling
Ye-Hong Chen, Wei Qin, Roberto Stassi +2
We propose a protocol for bosonic binomial-code nonadiabatic holonomic quantum computation in a system composed of an artificial atom ultrastrongly coupled to a cavity resonator. I…
Scalable quantum computer with superconducting circuits in the ultrastrong coupling regime
Roberto Stassi, Mauro Cirio, Franco Nori
So far, superconducting quantum computers have certain constraints on qubit connectivity, such as nearest-neighbor couplings. To overcome this limitation, we propose a scalable arc…
Scully-Lamb quantum laser model for parity-time-symmetric whispering-gallery microcavities: Gain saturation effects and non-reciprocity
Ievgen I. Arkhipov, Adam Miranowicz, Omar Di Stefano +4
We use a non-Lindbladian master equation of the Scully-Lamb laser model for the analysis of light propagation in a parity-time symmetric photonic system composed of coupled active…
