TELEPORTING AND SPLITTING ARBITRARY SINGLE-QUBIT INFORMATION USING A CLASS OF THREE-QUBIT W STATES
Jie Chi Yang, Yimin Liu, Xueqin Zuo, Zhanjun Zhang · International Journal of Quantum Information · 2009
Using a class of three-qubit W states as quantum channel, we present a quantum teleportation (QT) scheme and a quantum information splitting (QIS) scheme, respectively. We compare our schemes with two similar schemes proposed recently. It is found that our QT scheme reduces the operation difficulty in contrast to Agrawal and Pati's QT scheme [Phys. Rev. A74 (2006) 062320], and our QIS scheme is more applicable than Zheng's QIS scheme [Phys. Rev. A74 (2006) 054303] for the latter is only a special case of the former in some given conditions.
