Cross-Kerr-based information transfer processes
Jinhyoung Lee, M. Paternostro, C. Ogden +3
The realization of nonclassical states is an important task for many applications of quantum information processing. Usually, properly tailored interactions, different from goal to…
Enhanced dynamical entanglement transfer with multiple qubits
A. Serafini, M. Paternostro, M. S. Kim +1
We present two strategies to enhance the dynamical entanglement transfer from continuous variable (CV) to finite dimensional systems by employing multiple qubits. First, we conside…
Entanglement of mixed macroscopic superpositions: an entangling-power study
M. Paternostro, H. Jeong, M. S. Kim
We investigate entanglement properties of a recently introduced class of macroscopic quantum superpositions in two-mode mixed states. One of the tools we use in order to infer the…
Generation of a coherent superposition state on demand
M. S. Kim, M. Paternostro
We propose an experimentally feasible scheme to generate a superposition of travelling field coherent states using extremely small Kerr effect and an ancilla which could be a singl…
Joint measurements and Bell inequalities
Wonmin Son, Erika Andersson, Stephem M. Barnett +1
Joint quantum measurements of non-commuting observables are possible, if one accepts an increase in the measured variances. A necessary condition for a joint measurement to be poss…
Entanglement reciprocation between qubits and continuous variables
Jinhyoung Lee, M. Paternostro, M. S. Kim +1
We investigate how entanglement can be transferred between qubits and continuous variable (CV) systems. We find that one ebit borne in maximally entangled qubits can be fully trans…
