A closed-form necessary and sufficient condition for any two-qubit state to show hidden nonlocality w.r.t the Bell-CHSH inequality
Rajarshi Pal, Sibasish Ghosh
In this note, we discuss a closed-form necessary and sufficient condition for any two-qubit state to show hidden nonlocality w.r.t the Bell-CHSH inequality. This is then used to nu…

Entanglement sharing through noisy qubit channels: One-shot optimal singlet fraction
Rajarshi Pal, Somshubhro Bandyopadhyay, Sibasish Ghosh
Maximally entangled states--a resource for quantum information processing--can only be shared through noiseless quantum channels, whereas in practice channels are noisy. Here we as…
