Analytic Formulas for Quantum Discord of Special Families of N-Qubit States
Jianming Zhou, Xiaoli Hu, Honglian Zhang +1
Quantum discord, a key indicator of non-classical correlations in bipartite systems, has been recently extended to multipartite scenarios [Phys. Rev. Lett. 2020, 124:110401]. We pr…
Quantum discords of tripartite quantum systems
Jianming Zhou, Xiaoli Hu, Naihuan Jing
The quantum discord of bipartite systems is one of the best-known measures of non-classical correlations and an important quantum resource. In the recent work appeared in [Phys. Re…
Improved unitary uncertainty relations
Xiaoli Hu, Naihuan Jing
We derive strong variance-based uncertainty relations for arbitrary two and more unitary operators by re-examining the mathematical foundation of the uncertainty relation. This is…
Quantum discord of certain two-qubit states
Jianming Zhou, Xiaoli Hu, Naihuan Jing
Quantum discord is an effective measure of quantum correlation introduced by Olliver and Zurek. We evaluate analytically the quantum discord for a large family of non-X-states. Exa…
