Teleporting Noncommuting Qubits Require Maximal Entanglement
Sibasish Ghosh, Guruprasad Kar, Anirban Roy +2
Very recently, it was shown by Ghosh, Kar, Roy and Sen (\emph{Entanglement vs. Noncommutativity in Teleportation}, quant-ph/0010012) that if it is \emph{a priori} known that the st…
Entanglement Teleportation Through Cat-like States
Sibasish Ghosh, Guruprasad Kar, Anirban Roy +2
We first consider teleportation of entangled states shared between Claire and Alice to Bob1 and Bob2 when Alice and the two Bobs share a single copy of a GHZ-class state and where…
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…
Does Anti-Parallel Spin Always Contain more Information ?
Sibasish Ghosh, Anirban Roy, Ujjwal Sen
We show that the Bloch vectors lying on any great circle is the largest set S(L) for which the parallel states |n,n> can always be transformed into the anti-parallel states |n,-n>.…
