Linear-Optics-Based Bidirectional Controlled Remote State Preparation via Five-Photon Cluster-Type States for Quantum Communication Network

Cyclic controlled remote state preparation in the three-dimensional system

“…Since then, RSP has attracted much attention, various theoretical protocols for generalization of RSP have been proposed and experimental implementation of RSP have been presented . Recently, several novel protocols for joint RSP [51,[64][65][66][67][68][69][70][71][72][73][74], controlled bidirectional RSP (CBRSP) [75][76][77][78][79][80] and asymmetric CBRSP (ACBRSP) [81][82][83][84][85][86] have been proposed. More recently, a new protocol of cyclic controlled RSP (CCRSP) by using a tenqubit entangled state has been presented [87].…”

Asymmetric and deterministic bidirectional remote state preparation under the supervision of a third party

“…Recently, Cao and Nguyan [45] proposed a new RSP scheme, called deterministic controlled bidirectional RSP (CBRSP), which allows two distant parties to simultaneously and deterministically exchange their states under control of a third remote party in such a way that it cannot succeed without permission of the controller. Based on [45], several schemes of CBRSP were presented [46][47][48][49][50]. It is easy to see that all of the above schemes for CBRSP [45][46][47][48][49][50] are symmetrical-that is, in all these schemes, just a single-qubit state is transferred each way between the participants.…”

We find that so far no scheme has been reported for asymmetric CBRSP.…”
