Hilbert-Schmidt measure of pairwise quantum discord for three-qubit states
M. Daoud, R. Ahl Laamara, S. Seddik
The Hilbert-Schmidt distance between a mixed three-qubit state and its closest state is used to quantify the amount of pairwise quantum correlations in a tripartite system. Analyti…

A recursive approach for geometric quantifiers of quantum correlations in multiqubit Schrödinger cat states
M. Daoud, R. Ahl Laamara, S. Seddik
A recursive approach to determine the Hilbert-Schmidt measure of pairwise quantum discord in a special class of symmetric states of qubits is presented. We especially focus on…
