“…Compared with their scheme, our scheme is that Alice wants to transmit the state of single qubit a to Bob and Bob wants to transmit the state of two qubits to Alice. Compared with other low quality entanglement and any other schemes [103][104][105][106][107][108][109], our protocol has higher quality entanglement.…”

We propose a new protocol of asymmetric bidirectional controlled teleportation by using a seven-qubit cluster state as the quantum channel. That is to say Alice wants to transmit an arbitrary single-qubit state to Bob and Bob wants to transmit an arbitrary two qubit state to Alice via the control of the supervisor Charlie. One only need perform the Bell-state measurements and single-qubit measurement.

“…In their pioneering work Bennet et al used collective entanglement concentration procedure (i.e., Schmidt projective method). Since the pioneering works of Bennet et al, several ECPs and EPs are proposed [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. Initially most of the ECPs were proposed for non-maximally entangled Bell state.…”

“…In 2013, Ling-yan He [20] proposed a single nitrogen vacancy (N-V) center assisted ECP for a specific type of partially entangled W state. Very recently, ECPs for partially entangled GHZ states are proposed by Choudhury and Dhara [21] and Zhou et al [22], ECPs for 4-qubit cluster state are proposed by Choudhury and Dhara [23], Ting-Ting Xu et al [24] and Zhau et al [25], ECP for partially entangled NOON states is proposed by Zhou et al [26]. Clearly, much attention has recently been paid to develop ECPs for partially entangled states other than Bell state.…”

Three entanglement concentration protocols (ECPs) are proposed. The first ECP and a modified version of that are shown to be useful for the creation of maximally entangled cat and GHZ-like states from their nonmaximally entangled counterparts. The last two ECPs are designed for the creation of maximally entangled (n+ 1)-qubit state . It is also shown that W, GHZ, GHZ-like, Bell and cat states and specific states from the 9 SLOCC-nonequivalent families of 4-qubit entangled states can be expressed as(|Ψ0 |0 + |Ψ1 |1 ) and consequently the last two ECPs proposed here are applicable to all these states. Quantum circuits for implementation of the proposed ECPs are provided and it is shown that the proposed ECPs can be realized using linear optics. Efficiency of the ECPs are studied using a recently introduced quantitative measure (Phys. Rev. A 85, 012307 (2012)). Limitations of the measure are also reported.

“…The cluster states are harder to be destroyed by local operations than two-particle states and three-particle states [25]. A few schemes begin to mention the concentration for cluster states [26][27][28]. In 2013, Si et al presented an efficient three-step entanglement concentration for an arbitrary four-photon cluster state [26].…”

We present a scheme for locally concentrating a non-maximally entangled four-photon cluster state into a maximally-entangled four-photon cluster state. This scheme has a high success probability. The controlled-NOT (CNOT) gate is a crucial ingredient in this scheme, and we use a nearly deterministic CNOT gate, which is similar with that first introduced by Nemoto et al. (Phys. Rev. Lett., 2004, 93: 250502). This CNOT gate has a simple structure and does not need the strong nonlinearity.
