The disentangling power of unitaries
Lieven Clarisse, Sibasish Ghosh, Simone Severini +1
We define the disentangling power of a unitary operator in a similar way as the entangling power defined by Zanardi, Zalka and Faoro [PRA, 62, 030301]. A general formula is derived…
Continuous Variable Quantum Cryptography using Two-Way Quantum Communication
Stefano Pirandola, Stefano Mancini, Seth Lloyd +1
Quantum cryptography has been recently extended to continuous variable systems, e.g., the bosonic modes of the electromagnetic field. In particular, several cryptographic protocols…
Complementarity and Uncertainty in Mach-Zehnder Interferometry and beyond
Paul Busch, Christopher R. Shilladay
A coherent account of the connections and contrasts between the principles of com- plementarity and uncertainty is developed starting from a survey of the various formalizations of…
A generalization of boson normal ordering
Toufik Mansour, Matthias Schork, Simone Severini
In this paper we define generalizations of boson normal ordering. These are based on the number of contractions whose vertices are next to each other in the linear representation o…
Constructions of indecomposable positive maps based on a new criterion for indecomposability
William Hall
We give a criterion for a positive mapping on the space of operators on a Hilbert space to be indecomposable. We show that this criterion can be applied to two families of positive…
A (5,5) and (6,6) PPT edge state
Lieven Clarisse
Entangled states with a positive partial transpose (PPTES) have interest both in quantum information and in the theory of positive maps. In there is a conjecture by Sa…
