Bounds on mixed state entanglement

Bruno Leggio, Anna Napoli, Hiromichi Nakazato +1

In the general framework of $d \times d$ mixed states, we derive an explicit bound for bipartite NPT entanglement based on the mixedness characterization of the physical system. The…

Experimental investigation of quantum decay at short, intermediate and long times via integrated photonics

Andrea Crespi, Francesco V. Pepe, Paolo Facchi +5

The decay of an unstable system is usually described by an exponential law. Quantum mechanics predicts strong deviations of the survival probability from the exponential: indeed, t…

Analytically solvable $2 \times 2$ $P T$ -symmetry dynamics from su(1,1)-symmetry problems

R. Grimaudo, A. S. M. de Castro, H. Nakazato +1

A protocol for explicitly constructing the exact time-evolution operators generated by $2 \times 2$ time-dependent $P T$ -symmetry Hamiltonians is reported. Its mathematical applicab…
