Distinguishing two-qubit states using local measurements and restricted classical communication
Mark Hillery, Jihane Mimih
The problem of unambiguous state discrimination consists of determining which of a set of known quantum states a particular system is in. One is allowed to fail, but not to make a…
Quantum state filtering and discrimination between sets of Boolean functions
Janos A. Bergou, Ulrike Herzog, Mark Hillery
The problem of quantum state filtering consists of determining whether an unknown quantum state, which is chosen from a known set of states, is either a particular, specified state…
Quantitative conditional quantum erasure in two-atom resonance fluorescence
Matthias Jakob, Janos Bergou
We present a conditional quantum eraser which erases the a priori knowledge or the predictability of the path a photon takes in a Young-type double-slit experiment with two fluores…
Implementation of quantum maps by programmable quantum processors
Mark Hillery, Mario Ziman, Vladimir Buzek
A quantum processor is a device with a data register and a program register. The input to the program register determines the operation, which is a completely positive linear map,…
Degree of entanglement in a quantum measurement process
Matthias Jakob, Yonatan Abranyos, Janos A. Bergou
We suggest a quantum measurement model in an ion trap which specifies the probability distribution of two, distinct internal ground states of a trapped four-level ion. The external…
