Hierarchy of hidden nonlocality: A genuine activation of Incompletability
Soumajit Das, Shampa Mondal, Preeti Parashar +1
Quantum nonlocality admits several operational manifestations, one of which emerges from sets of orthogonal quantum states that cannot be perfectly distinguished by local operation…
Incompleteness is necessary for activation of nonlocality without entanglement
Atanu Bhunia, Saronath Halder, Preeti Parashar +1
A set of orthogonal product states is said to exhibit "quantum nonlocality without entanglement" if it is locally indistinguishable, i.e. no sequence of local operations and classi…
Free encoding capacity: A universal unit for quantum resources
Shampa Mondal, Soumajit Das, Preeti Parashar +1
A perfect d-dimensional quantum channel can convey log d-bits of classical information by encoding messages in d-orthogonal quantum states. Alternatively, for every quantum state a…
Lost and found charge in quantum batteries
Debanjan Dey Sarkar, Mallika Mondal, Preeti Parashar +1
Quantum batteries are prone to losing their stored charge, when interacting with a thermal environment. However, getting a limited assistance from the thermal environment, is it po…
