Experimental single qubit quantum secret sharing.
We present a simple and practical protocol for the solution of a secure multiparty communication task, the secret sharing, and its proof-of-principle experimental realization. In this protocol, a secret is split among several parties in a way that its reconstruction requires the collaboration of the participating parties. In our scheme the parties solve the problem by sequential transformations...
متن کاملNOVEL QUBIT QUANTUM CRYPTOGRAPHY PROTOCOLS Quantum Secret Sharing
This report summarises the ongoing work in QuComm on the demonstration of novel quantum communication protocols, in particular multi-party protocols or protocols which use more than 2-states (or more than one qubit). Such new protocols will extend the capabilities of quantum communication by increasing the channel capacity, by making the systems less sensitive to channel noise. Examples of such...
متن کاملMultiparty Quantum Secret Sharing Based on Entanglement Swapping
A multiparty quantum secret sharing (QSS) protocol is proposed by using swapping quantum entanglement of Bell states. The secret messages are imposed on Bell states by local unitary operations. The secret messages are split into several parts and each part is distributed to a party so that no action of a subset of all the parties but their entire cooperation is able to read out the secret messa...
متن کاملMultipartite Quantum Secret Sharing using a Single Not-So-Weak Qubit
We propose a new quantum secret sharing scheme using a single non-entangled qubit. In the scheme, by transmitting a qubit to the next party sequentially, a sender can securely transmit a secret message to N receivers who could only decode the message cooperatively after randomly shuffling the polarization of the qubit. We explain this quantum secret sharing scheme into the one between a sender ...
متن کاملMultiparty secret sharing of quantum information based on entanglement swapping
A protocol of multiparty secret sharing of quantum information based on entanglement swapping is analyzed. In this protocol, Bell states are needed in order to realize the quantum information secret sharing and it is convenient to realize the quantum secret sharing among the members of any subset of users. 2004 Elsevier B.V.
