Conclusive inner product modification
Luis Roa, A. Delgado, M. L. Ladron de Guevara
The task of changing the overlap between two quantum states can not be performed by making use of a unitary evolution only. However, by means of a unitary-reduction process it can…

Unambiguous modification of nonorthogonal single and two photon polarization states
F. A. Torres-Ruiz, J. Aguirre, A. Delgado +5
In this work we propose a probabilistic method which allows an unambiguous modification of two non-orthogonal quantum states. We experimentally implement this protocol by using two…
