Towards optimized suppression of dephasing in systems subject to pulse timing constraints
Thomas E. Hodgson, Lorenza Viola, Irene D'Amico
We investigate the effectiveness of different dynamical decoupling protocols for storage of a single qubit in the presence of a purely dephasing bosonic bath, with emphasis on comp…
Effect of confinement potential geometry on entanglement in quantum dot-based nanostructures
S. Abdullah, J. P. Coe, I. D'Amico
We calculate the spatial entanglement between two electrons trapped in a nanostructure for a broad class of confinement potentials, including single and double quantum dots, and co…
Better Late than Never: Information Retrieval from Black Holes
Samuel L. Braunstein, Stefano Pirandola, Karol Życzkowski
We show that, in order to preserve the equivalence principle until late times in unitarily evaporating black holes, the thermodynamic entropy of a black hole must be primarily entr…
The geometric measure of multipartite entanglement and the singular values of a hypermatrix
Joseph J. Hilling, Anthony Sudbery
It is shown that the geometric measure of entanglement of a pure multipartite state satisfies a polynomial equation, generalising the characteristic equation of the matrix of coeff…
On the notion of coexistence in quantum mechanics
P. Busch, J. Kiukas, P. Lahti
The notion coexistence of quantum observables was introduced to describe the possibility of measuring two or more observables together. Here we survey the various different formali…
Confidential direct communications: a quantum approach using continuous variables
Stefano Pirandola, Samuel L. Braunstein, Seth Lloyd +1
We consider the problem of privacy in direct communications, showing how quantum mechanics can be useful to guarantee a certain level of confidentiality. In particular, we review a…
