Perfect Teleportation of an Arbitrary Two-Qubit State via GHZ-Like States

A complete classification of quantum public-key encryption protocols

“…So the encryption algorithm should be belong to quantum space. Through this analysis, we can confirm that kind 5,6,9,10,17,18,21,22,25,26 Similarly, if either ciphertext or private-key is quantum during the process of decryption, the plaintext must be quantum states. The reason is the same with encryption processing.…”

A probabilistic quantum communication protocol using mixed entangled channel

“…Suppose two quantum channels are shared between Alice and Bob which are one non maximally entan gled GHZ like state and one non maximally entan gled Bell state given by, and where 's are all real and non zero and and , and the particles 3, 4, and 6 are in the possession of the sender Alice, the particle 5 and 7 belong to the receiver Bob. It may be noted that maximally entangled GHZ like state + has been used in com munication protocols in [13].…”

“…Origi nally the quantum teleportation was presented by Bennett et al [1] for arbitrary single qubit quantum states by using a maximally entangled Bell state. After that several theoretical and experimental aspects of different teleportation protocols with various types of quantum resources appeared in the literature, some of which are noted in [2][3][4][5][6][7][8][9][10][11][12][13][14][15]. We describe some of the works below.…”

“…In 2013, Nandi and Mazumdar [12] presented a teleportation protocol of a more general two qubit state using the GHZ like state as quantum channel. In 2014, Zhu [13] presented a quantum teleportation of an arbitrary two qubit state via maximally entangled GHZ like states. In 2011, Nie et al [14] attempted the teleportation of a three qubit state which is an arbitrary GHZ type state using four qubit cluster states as quantum channel.…”

Bidirectional controlled quantum teleportation by a genuine entangled 9-qubit state

“…Bell态、GHZ态、W态以及d级的Bell态、d级的GHZ 态等, 学者们研究了各种各样的纠缠态作为量子信道 的隐形传态方案, 例如: (1) 提出了基于各种Bell态、 GHZ态、W态及其积态作为量子信道的隐形传态方 案 [11][12][13][14][15][16][17][18][19] ; (2) 提出了基于各种d级Bell态、d级GHZ态及 其积态的量子隐形传态方案 [20][21][22][23] ;…”
