Two-state Teleportation
Quantum teleportation with additional a priori information about the input state achieves higher fidelity than teleportation of a completely unknown state. However, perfect teleportation of two non-orthogonal input states requires the same amount of en-tanglement as perfect teleportation of an unknown state, namely one ebit. We analyse how well two-state teleportation can be achieved using ever...
متن کاملProbabilistic teleportation of two - particle entangled state
In this report, two different probabilistic teleportations of a two-particle entangled state by pure entangled three-particle state are shown. Their successful probabilities are different. 03.65.Bz, 03.67.-a Typeset using REVTEX ∗E-mail: [email protected] †E-Mail: [email protected] 1 Quantum teleportation, proposed by Bennett et.al [1], is the process that transmits an unknown two-state particl...
متن کاملMethods for reliable teleportation
Recent experimental results and proposals towards implementation of quantum teleportation are discussed. It is proved that reliable ~theoretically, 100% probability of success! teleportation cannot be achieved using the methods applied in recent experiments, i.e., without quantum systems interacting with one another. Teleportation proposals involving atoms and electromagnetic cavities are revie...
متن کاملOptimal teleportation with a mixed state of two qubits.
We consider a single copy of a mixed state of two qubits and derive the optimal trace-preserving local operations assisted by classical communication such as to maximize the fidelity of teleportation that can be achieved with this state. These optimal local operations turn out to be implementable by one-way communication and always yield a teleportation fidelity larger than 2/3 if the original ...
