Entangling Power of Permutations
Lieven Clarisse, Sibasish Ghosh, Simone Severini +1
The notion of entangling power of unitary matrices was introduced by Zanardi, Zalka and Faoro [PRA, 62, 030301]. We study the entangling power of permutations, given in terms of a…
Probabilistic cloning and signalling
Sibasish Ghosh, Guruprasad Kar, Samir Kunkri +1
We give a proof of impossibility of probabilistic exact cloning of any three different states of a qubit. The simplicity of the proof is due to the use of a surprising res…
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…
