The separability versus entanglement problem
Aditi Sen De, Ujjwal Sen, Maciej Lewenstein +1
We review the problem of discriminating entangled states from separable states for bipartite systems. We formally define what entangled states are, present some important criteria…
Cloning of orthogonal mixed states entails irreversibility
Michal Horodecki, Aditi Sen De, Ujjwal Sen
Orthogonal pure states can be cloned as well as deleted. However if there is an initial disorder in the system, that is for orthogonal mixed states, one cannot perform deletion. An…
No-deleting and no-cloning principles as consequences of conservation of quantum information
Michal Horodecki, Ryszard Horodecki, Aditi Sen De +1
We show that the no-deleting and no-cloning principles are implications of information conservation principle. This is unlike in classical physics, where cloning and deleting are p…
Entanglement vs. Noncommutativity in Teleportation
Sibasish Ghosh, Guruprasad Kar, Anirban Roy +1
We provide an alternative simple proof of the necessity of entanglement in quantum teleportation by using the no-disentanglement theorem. We show that this is true even when the st…
An Upper Bound on the Number of States in an Unextendible Product Basis
