Weak measurements with a qubit meter
Shengjun Wu, Klaus Mølmer
We derive schemes to measure the so-called weak values of quantum system observables by coupling of the system to a qubit meter system. We highlight, in particular, the meaning of…

Optimum Unambiguous Discrimination of Linearly Independent Pure States
Shengshi Pang, Shengjun Wu
Given linearly independent pure states and their prior probabilities, we study the problem of optimum unambiguous discrimination of these states. We derive the properties of th…

Correlations in local measurements on a quantum state, and complementarity as an explanation of nonclassicality
Shengjun Wu, Uffe V. Poulsen, Klaus Mølmer
We consider the classical correlations that two observers can extract by measurements on a bipartite quantum state, and we discuss how they are related to the quantum mutual inform…
