Coherence, Path-Predictability and I-Concurrence: A Triality
Abhinash Kumar Roy, Neha Pathania, Nitish Kumar Chandra +2
It is well known that fringe contrast is not a good quantifier of the wave nature of a quanton in multipath interference. A new interference visibility, based on the Hilbert-Schmid…
Dissipative dynamics of quantum correlation quantifiers under decoherence channels
Nitish Kumar Chandra, Sarang S. Bhosale, Prasanta K. Panigrahi
In this work, we investigate the dynamics of quantum correlations captured by entropic and geometric measures of discord under the influence of dissipative channels for widely used…
'Complementarity' in paraxial and non-paraxial optical beams
Abhinash Kumar Roy, Nitish Kumar Chandra, Soumik Mahanti +1
Establishing the correspondence of two dimensional paraxial and three dimensional non-paraxial optical beams with the qubit and qutrit systems respectively, we derive a complementa…
Geometric quantification of multiparty entanglement through orthogonality of vectors
Abhinash Kumar Roy, Nitish Kumar Chandra, S Nibedita Swain +1
The wedge product of vectors has been shown to yield the generalised entanglement measure I-concurrence, wherein the separability of the multiparty qubit system arises from the par…
