Multipartite Generalization of Geometric measure of Discord

Ali Saif M. Hassan, Pramod S. Joag

Radhakrishnan et.al [Phys. Rev. Lett. 124, 110401 (2020)] proposed a generalization of quantum discord to multipartite systems, which is consistency with the conventional definitio…

Invariance of quantum correlations under local channel for a bipartite quantum state

Ali Saif M. Hassan, Pramod S. Joag

We show that the quantum discord and the measurement induced non-locality (MiN) in a bipartite quantum state is invariant under the action of a local quantum channel if and only if…

Measurement-Induced Nonlocality in an -partite quantum state

Ali Saif M. Hassan, Pramod S. Joag

We generalize the concept of measurement-induced non-locality (MiN) to -partite quantum states. We get exact analytical expressions for MiN in an -partite pure and -qubit…

Geometric measure of quantum discord and total quantum correlations in a N-partite quantum state

Ali Saif M. Hassan, Pramod S. Joag

Quantum discord, as introduced by Olliver and Zurek [Phys. Rev. Lett. \textbf{88}, 017901 (2001)], is a measure of the discrepancy between quantum versions of two classically equiv…

Simulation of a Partially Entangled Two Qubit State Correlation with one PR-Box and one M-box

Ali Ahanj, Pramod S. Joag

We present a protocol to simulate the quantum correlation implied by non maximally entangled two qubit states, in the worst case scenario. This protocol makes a single use of PR-bo…

Tight lower bound to the geometric measure of quantum discord

Ali Saif M. Hassan, Behzad Lari, Pramod S. Joag

Dakic, Vedral and Brukner [Physical Review Letters \tf{105},190502 (2010)] gave a geometric measure of quantum discord in a bipartite quantum state as the distance of the state fro…
