Controlled Teleportation Protocols

Abstract

In this chapter, teleportation under supervision, that is, controlled teleportation process is described. Particularly, we describe controlled bidirectional and cyclic teleportation protocols. Some other works on teleportation under supervision are listed in [ 30 , 31 , 53 , 73 , 74 , 87 , 90 , 91 , 93 , 124 , 141 , 142 , 150 , 154 , 172 , 195 , 202 ]. Particularly, teleportation protocols under multiple and hierarchical control have appeared in works like [ 17 , 65 , 138 , 182 , 183 , 184 , 192 ].

Bidirectional Teleportation Protocols

Binayak S. Choudhury, Soumen Samanta

In this chapter, the bidirectional teleportation process is described which is mutual exchange of quantum states between two distant parties connected through entanglement. Here, both parties act as sender and receiver. Bidirectional teleportation schemes of various kinds have been discussed in works like [ 19 , 46 , 59 , 137 , 159 , 160 , 162 , 166 , 203 ].

Control of Noise in Teleportation Processes

Binayak Samadder Choudhury, Soumen Samanta

In this chapter, two mechanisms for minimizing the effect of noise on the teleportation protocol are presented. The fidelity improvement is analyzed with respect to the variations of control parameters. There are several works on this topic in recent times [ 61 , 75 , 88 , 89 , 128 , 129 , 146 , 175 , 185 ].

Probabilistic Teleportation Protocols

Binayak S. Choudhury, Soumen Samanta

The protocols presented in this chapter are probabilistic teleportation protocols in which there are cases of failures with certain probabilities. Probabilistic teleportation schemes of various kinds have been discussed in works like [ 1 , 41 , 45 , 76 , 82 , 85 , 98 , 118 , 135 , 168 , 169 , 180 ]. Generally the quantum resources used in these protocols are not maximally entangled. This is one explanation for the probabilistic nature of these protocols. The justification of studying these protocols is that the generation and preservation of resources for these protocols are less difficult compared to that of those where maximally entangled states are used. Also, there is a class of resumable protocols in which the probabilistic teleportation process can be repeated in the case where the attempt fails in the first place [ 21 , 52 , 104 , 105 ].

Multi-hop Teleportation Schemes

Binayak S. Choudhury, Soumen Samanta

In this chapter, the multi-hop teleportation process is described in which there are intermediate nodes between the sender and the receiver. Protocols with and without controller are presented. These protocols with intermediate nodes are needed in cases of long distance teleportation where the shared entangled resources become vulnerable to environment disturbances.
