Deterministic joint remote state preparation of arbitrary two- and three-qubit states∗
We propose a novel deterministic protocol that two senders are capable of remotely preparing arbitrary twoand three-qubit states for a remote receiver using EPR pairs and GHZ state as the quantum channel. Compared with the existing deterministic protocols [An et al. 2011 Phys. Lett. A 375 3570 and Chen et al. 2012 J. Phys. A: Math. Theor. 45 055303], the quantum resources and classical informat...
متن کاملEffect of quantum noise on deterministic joint remote state preparation of a qubit state via a GHZ channel
Quantum secure communication brings a new direction for information security. As an important component of quantum secure communication, deterministic joint remote state preparation (DJRSP) could securely transmit a quantum state with 100% success probability. In this paper, we study how the efficiency of DJRSP is affected when qubits involved in the protocol are subjected to noise or decoheren...
متن کاملGeneralized Remote Preparation of Arbitrary m-qubit Entangled States via Genuine Entanglements
Herein, we present a feasible, general protocol for quantum communication within a network via generalized remote preparation of an arbitrary m-qubit entangled state designed with genuine tripartite Greenberger–Horne–Zeilinger-type entangled resources. During the implementations, we construct novel collective unitary operations; these operations are tasked with performing the necessary phase tr...

متن کاملControlled Remote State Preparation via General Pure Three-Qubit State
The protocols for controlled remote state preparation of a single qubit and a general two-qubit state are presented in this paper. The general pure three-qubit states are chosen as shared quantum channel, which are not Local operations and classical communication (LOCC) equivalent to the mostly used GHz state. This is the first time that general pure three-qubit states have been introduced to c...
