“…The qubits in an entangled state have some kind of long-range correlation, and when one or more qubits are measured, the remaining qubits will collapse instantly. Due to this characteristic, quantum entanglement has been used in many quantum information processing tasks, such as quantum key distribution [1][2][3][4][5][6], quantum secure direct communication [7][8][9][10][11][12], remote state preparation [13][14][15][16], quantum operation transmitting and sharing [17][18][19][20][21][22], and so on.…”

Based on a six-qubit entangled state, a quantum information processing scheme for teleporting a distinctive six-qubit state is presented. In the scheme, only Bell-state measurements and two-qubit controlled-NOT gate operations as well as some single-qubit transformed operations are needed. Compared with a rival scheme put forwarded by Tan et al. [Int. J. Theor. Phys. 55, 155 (2016)], the present scheme is more simpler and easier to execute because it does not require to make the six-qubit entangled state measurement. Besides, it is deterministic and feasible in terms of the current experimental technologies.
