A scheme for controlled quantum state swapping is presented using maximally entangled five-qubit state,i.e.,Alice wants to transmit an entangled state of particle a to Bob and at the same time Bob wants to transmit an...
Recently, Gao et al. [Opt. Commun. 283 (2010) 192] pointed out that Wang et al,'s multiparty controlled quantum secure direct communication (CQSDC) protocol [Opt. Commun. 266 (2006) 732] has the information lea...
