Alice and Bob through a quantum mirror
M. Uria, C. Hermann-Avigliano, P. Solano +1
A quantum mirror is a device whose optical response, that is, transmission and reflection, can be controlled by a single qubit. Here, we propose the use of quantum mirrors as nodes…

Discrimination of metric theories
F. J. Lobo, M. Rivera-Tapia, G. Rubilar +2
We study the possibility of discriminating between metric theories within the Parametrized Post-Newtonian formalism. In this approach, the two-dimensional quantum state of a massiv…

Estimation of high-dimensional unitary transformations saturating the Quantum Cramér-Rao bound
J. Escandón-Monardes, D. Uzcátegui, M. Rivera-Tapia +2
We propose an estimation procedure for -dimensional unitary transformations. For , the unitary transformations close to the identity are estimated saturating the quantum Cr…
