Simultaneous perfect teleportation of three 2-qubit states

Simultaneous perfect teleportation of three 2-qubit states In this paper we show that simultaneous transfer of certain 2-qubit states by three different senders to three different receivers is possible with the help of a single shared entanglement resource. The multi-task is accomplished through a single protocol. There is a supervisor in the type of teleportation process we present here. All the senders perform their quantum measurements in the GHZ-type basis. The protocol is substantially simplified due to the fact that in each measurement of the senders, fifty percent of the basis elements appear. This also leads to an increased efficiency of our protocol which we calculate here. The type of protocol is perfect teleportation protocol. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Quantum Information Processing Springer Journals

Abstract

In this paper we show that simultaneous transfer of certain 2-qubit states by three different senders to three different receivers is possible with the help of a single shared entanglement resource. The multi-task is accomplished through a single protocol. There is a supervisor in the type of teleportation process we present here. All the senders perform their quantum measurements in the GHZ-type basis. The protocol is substantially simplified due to the fact that in each measurement of the senders, fifty percent of the basis elements appear. This also leads to an increased efficiency of our protocol which we calculate here. The type of protocol is perfect teleportation protocol.
