Quantum Field Theory and Coalgebraic Logic in Theoretical Computer Science
Gianfranco Basti, Antonio Capolupo, Giuseppe Vitiello
In this paper we suggest that in the framework of the Category Theory it is possible to demonstrate the mathematical and logical \textit{dual equivalence} between the category of t…
Experimental pre-assessing entanglement in Gaussian states mixing
A. Pecoraro, D. Buono, G. Nocerino +3
We suggest and demonstrate a method to assess entanglement generation schemes based on mixing of Gaussian states at a beam splitter (BS). Our method is based on the fidelity criter…
Quantum coherence of Gaussian states
Daniela Buono, Gaetano Nocerino, Giuseppe Petrillo +3
We introduce a geometric quantification of quantum coherence in single-mode Gaussian states and we investigate the behavior of distance measures as functions of different physical…
Exact electronic bands for a periodic Poschl-Teller potential
Francesco Di Filippo, Canio Noce
We show that supersymmetry is a simple but powerful tool to exactly solve quantum mechanics problems. Here, the supersymmetric approach is used to analyse a quantum system with per…
Non-Gaussian entanglement swapping
F. Dell'Anno, D. Buono, G. Nocerino +2
We investigate the continuous-variable entanglement swapping protocol in a non-Gaussian setting, with non- Gaussian states employed either as entangled inputs and/or as swapping re…
Quench of symmetry broken ground states
Salvatore Marco Giampaolo, Giuseppe Zonzo
We analyze the problem of how different ground states associated to the same set of the Hamiltonian parameters evolve after a sudden quench. To realize our analysis we define a qua…
