Local Distinguishability of Any Three Quantum States
Somshubhro Bandyopadhyay, Jonathan Walgate
We prove that any three linearly independent pure quantum states can always be locally distinguished with nonzero probability regardless of their dimension, entanglement, or multip…
Superadditivity of distillable entanglement From Quantum Teleportation
Somshubhro Bandyopadhyay, Vwani Roychowdhury
We show that the phenomenon of superadditivity of distillable entanglement observed in multipartite quantum systems results from the consideration of states created during the exec…
Duality for monogamy of entanglement
Somshubhro Bandyopadhyay, Gilad Gour, Barry C. Sanders
We establish duality for monogamy of entanglement: whereas monogamy of entanglement inequalities provide an upper bound for bipartite sharability of entanglement in a multipartite…
