Witnessed entanglement and the geometric measure of quantum discord
Tiago Debarba, Thiago O. Maciel, Reinaldo O. Vianna
We establish relations between geometric quantum discord and entanglement quantifiers obtained by means of optimal witness operators. In particular, we prove a relation between neg…
Quantifying Quantum Correlations in Fermionic Systems using Witness Operators
Fernando Iemini, Thiago O. Maciel, Tiago Debarba +1
We present a method to quantify quantum correlations in arbitrary systems of indistinguishable fermions using witness operators. The method associates the problem of finding the op…
Experimental implementation of a NMR entanglement witness
J. G. Filgueiras, T. O. Maciel, R. E. Auccaise +3
Entanglement witnesses (EW) allow the detection of entanglement in a quantum system, from the measurement of some few observables. They do not require the complete determination of…
