“…Different variations of RSP have been studied by researchers. Deterministic RSP has the successful probability of one hundred percent [9][10][11]. It could be fulfilled via Cluster-type state [12], χ state [10], Brown state [13], entangled six-qubit state [14] and so on.…”

Joint remote state preparation is an important method to transmit quantum information with more senders and higher security. In this paper, we present a deterministic joint remote state preparation scheme in multi-hop network with two senders and $N$ intermediate parties, using only projective measurements and recovery operations. We describe the scheme under the framework of density matrix to investigate the performance of the scheme in noisy environment. The relation of fidelity, noise rate and the number of intermediate nodes is given for three types of noise. It is revealed that the average fidelity attains its minimum when the noise rate is at the most uncertain point, decreases monotonically as the number of intermediate nodes increases. However, in some special cases, the average fidelity of the multi-hop scheme is greater than some existing one step joint remote state preparation scheme.

“…Based on the laws of quantum mechanics, during the past years, many efforts have been devoted to the research of quantum anonymous voting (QAV) in order to design a high secure voting scheme. Furthermore, the fundamental researches of quantum computation and information, such as quantum teleportation, [2,3] quantum states preparation, [4,5] and quantum memory for free, [6,7] have laid a foundation for the implementation of quantum voting schemes. In 2005, Christandl and Wehner [8] proposed a quantum communication protocol that could anonymously transmit classical bits using shared quantum states and classical broadcast channels, which was the first time that quantum anonymous voting was proposed.…”

Based on traveling ballot mode, we propose a secure quantum anonymous voting via Greenberger–Horne–Zeilinger(GHZ) states. In this scheme, each legal voter performs unitary operation on corresponding position of particle sequence to encode his/her voting content. The voters have multiple ballot items to choose rather than just binary options ”yes” or ”no”. After counting votes phase, any participant who is interested in voting results can obtain the voting results. To improve the efficiency of the traveling quantum anonymous voting scheme, an optimization method based on grouping strategy is also presented. Compared with the most existing traveling quantum voting schemes, the proposed scheme is more practical because of its privacy, verifiability and nonrepeatability. Furthermore, the security analysis shows that the proposed traveling quantum anonymous voting scheme can prevent various attacks and ensure high security.

“…[33] Remote state preparation schemes in noisy environments have also been studied. [34][35][36][37][38][39][40][41][42] Equatorial state is a special class of quantum states of the Bloch sphere. In contrast to general quantum states, some of the equatorial state's information is known.…”

We investigate the influence of noisy environment on the remote preparation of the multi-qubit equatorial state, and specifically deduce the final states and fidelities of the remote preparation of the three-qubit and four-qubit equatorial states under diverse types of noisy environment, namely amplitude damping, bit flip, phase damping, phase flip, bit-phase flip, depolarization and non-Markov environments. The results show that when the decoherence factors of the front six noise are equal, the influence degrees of phase damped noise, bit flip noise, phase flip noise and bit-phase flip noise are similar, while the information loss caused by amplitude damped noise and depolarizing noise is less. In particular, the bit flip noise and depolarizing noise may have more complex effects on the remote state preparation (RSP) schemes depending on the phase information of target states, even the ideal cases that the fidelity values are always 1 for specific phase relations. In the non-Markov environment, owing to the back and forth of information between the environment and systems, fidelities exhibit oscillating behavior and the minimum value may stay greater than zero for a long evolutionary time. These results are expected to have potential applications for understanding and avoiding the influence of noise on remote quantum communication and quantum networks.
