“…Indeed any particle pair in the GHZ state after tracing out the rest of the particles is maximally mixed. This is similar to quantum state sharing [9][10][11][12][13][14][15][16][17], whose basic idea is to let several receivers share an unknown quantum state under cooperations. In general, almost schemes of the quantum state sharing may be used to control teleportation with or without a little modification, and vice versa [18][19][20].…”

Two schemes, introducing the projective operator and the auxiliary qubit respectively, for controlled dense coding are investigated by using a three-qubit symmetric state with entanglement, where the supervisor (Cliff) can control an average amount of information transmitted from the sender (Alice) to the receiver (Bob) by adjusting the measurement angle θ . We show that the results for the average amounts of information are unique from the different two schemes. The schemes may be extended to many-qubit systems.

“…Applying the theory of quantum mechanics in the field of information, many interesting developments have been produced in last decades [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], such as quantum teleportation [1], quantum dense coding [2], quantum secret sharing [3], remote state preparation [4], and so on. Quantum teleportation was first proposed by Bennett et al [1] in 1993.…”

Abstract. We present a novel tripartite scheme for remotely preparing an arbitrary two-qubit state with two three-qubit entanglements. By using a proper positive operator-valued measure (POVM), it is shown that the remote two-qubit preparation can be realized in either distant ministrant's place in a probabilistic manner via their collaboration. We also explore its applications to six special ensembles of state in detail. The extensive investigations show that the remote preparation can be achieved with higher probability provided that the prepared state belongs to the six special ensembles.

“…Recently, Lance et al [17] proposed a scheme for QSS of quantum information, called as the quantum state sharing (QSTS), where the secret is an unknown quantum state, to differentiate from the QSS of classical information. QSTS is also usually named as quantum information splitting (QIS), and various kinds of QIS (or QSTS) schemes have been presented [18][19][20][21][22][23][24][25][26][27][28].…”
