Quantifying concurrence of two-qubit quantum states on a quantum computer

P. V. Sapriianchuk, Kh. P. Gnatenko

(íå ìåíøå 1800 çíàê³â) The concurrence of two-qubit quantum states is considered. Relation between the concurrence and the parameters of an arbitrary two-qubit quantum state is presented and quantified with quantum computing. For this purpose the mean values of spin operators are calculated on a quantum device. Results obtained on a quantum computer are in a good agreement with theoretical ones.
