Limitations on separable measurements by convex optimization
Somshubhro Bandyopadhyay, Alessandro Cosentino, Nathaniel Johnston +3
We prove limitations on LOCC and separable measurements in bipartite state discrimination problems using techniques from convex optimization. Specific results that we prove include…
Unambiguous discrimination of linearly independent pure quantum states: Optimal average probability of success
Somshubhro Bandyopadhyay
We consider the problem of unambiguous (error-free) discrimination of N linearly independent pure quantum states with prior probabilities, where the goal is to find a measurement t…
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…
