Extended Bargmann FDA and non-relativistic gravity
Ariana Muñoz, Gustavo Rubio, Sebastián Salgado
In this paper we consider the construction of a free differential algebra as an extension of the extended Bargmann algebra in arbitrary dimensions. This is achieved by introducing…

Threshold effect for probabilistic entanglement swapping
Luis Roa Oppliger, Torben L. Purz, Ariana Muñoz +3
The basic \emph{entanglement swapping protocol} allows to project two qubits, which have never interacted, onto a maximally entangled state. For deterministic swapping, the key ing…

Tomography from collective measurements
A. Muñoz, A. B. Klimov, M. Grassl +1
We discuss the tomography of -qubit states using collective measurements. The method is exact for symmetric states, whereas for not completely symmetric states the information a…
