Online optimal exact identification of a quantum change point
Gael Sentís, Esteban Martínez-Vargas, Ramon Muñoz-Tapia
We consider online detection strategies for identifying a change point in a stream of quantum particles allegedly prepared in identical states. We show that the identification of t…
Optimal discrimination of quantum states with a fixed rate of inconclusive outcomes
E. Bagan, R. Munoz-Tapia, G. A. Olivares-Renteria +1
In this paper we present the solution to the problem of optimally discriminating among quantum states, i.e., identifying the states with maximum probability of success when a certa…
Optimal scheme for estimating a pure qubit state via local measurements
E. Bagan, M. Baig, R. Munoz-Tapia
We present the optimal scheme for estimating a pure qubit state by means of local measurements on N identical copies. We give explicit examples for low N. For large N, we show that…
