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…
Submaximal Integral Domains
A. Azarang
It is proved that if is a and is a -algebra, such that , then has a maximal subring. In particular, if is a ring which either contains…
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…
