Controlled Quantum Teleportation Schemes Using Generalized Bell Bases

In view of the problem that there is only one typical Bell basis for QT (Quantum Teleportation), three new GBBs (Generalized Bell Bases) are obtained by transforming unitarily the Hadamard gates with the methods of Pauli gates in the quantum circuit of the traditional Bell basis, and four Bell bases have an identical general formula. Three controlled-QT schemes are proposed based on these GBBs. The changed processes of quantum entangled states during QT in these schemes are derived by using the similar method of the traditional Bell basis. The result analyses of quantum state collapses of controlled-QT show that more two-qubit quantum entanglement resources of Bell states can be available. These schemes can be considered as the beneficial supplements for current QT work with GBS (Generalized Bell State).
