New Bell inequalities for three-qubit pure states
Arpan Das, Chandan Datta, Pankaj Agrawal
We introduce a set of Bell inequalities for a three-qubit system. Each inequality within this set is violated by all generalized GHZ states. More entangled a generalized GHZ state…
Quantum ratchet in disordered quantum walk
Sagnik Chakraborty, Arpan Das, Arindam Mallick +1
Symmetrically evolving discrete quantum walk results in dynamic localization with zero mean displacement when the standard evolution operations are replaced by a temporal disorder…
Towards laboratory detection of topological vortices in superfluid phases of QCD
Arpan Das, Shreyansh S. Dave, Somnath De +1
Topological defects arise in a variety of systems, e.g. vortices in superfluid helium to cosmic strings in the early universe. There is an indirect evidence of neutron superfluid v…
