Multi-copy adaptive local discrimination: Strongest possible two-qubit nonlocal bases
Manik Banik, Tamal Guha, Mir Alimuddin +3
Ensembles of composite quantum states can exhibit nonlocal behaviour in the sense that their optimal discrimination may require global operations. Such an ensemble containing N pai…
Unextendible product bases, bound entangled states, and the range criterion
Pratapaditya Bej, Saronath Halder
An unextendible product basis (UPB) is a set of orthogonal product states which span a subspace of a given Hilbert space while the complementary subspace contains no product state.…
Locally distinguishing quantum states with limited classical communication
Saronath Halder, Chirag Srivastava
We consider different settings of the task to distinguish pure orthogonal quantum states under local operations and a limited amount of classical communication. In the first settin…
Genuinely Nonlocal Product Bases: Classification and Entanglement Assisted Discrimination
Sumit Rout, Ananda G. Maity, Amit Mukherjee +2
An orthogonal product basis of a composite Hilbert space is genuinely nonlocal if the basis states are locally indistinguishable across every bipartition. From an operational point…
Distinguishability classes, resource sharing, and bound entanglement distribution
Saronath Halder, Ritabrata Sengupta
Suppose a set of -partite, , pure orthogonal fully separable states is given. We consider the task of distinguishing these states perfectly by local operations and class…
Genuinely entangled subspace with all-encompassing distillable entanglement across every bipartition
Sristy Agrawal, Saronath Halder, Manik Banik
In a multipartite scenario quantum entanglement manifests its most dramatic form when the state is genuinely entangled. Such a state is more beneficial for information theoretic ap…
