“…So far, the research of multiparty RSP via non-maximally entangled channels has made dramatic progress. [26][27][28][29][30][31][32] Recently, Chen et al [28] put forward the controlled RSP of two-qubit state using an eight-qubit partially entangled channel. In 2017, a multiparty RSP scheme was introduced in Ref.…”

Due to the unavoidable interaction between the quantum channel and its ambient environment, it is difficult to generate and maintain the maximally entanglement. Thus, the research on multiparty information transmission via non-maximally entangled channels is of academic value and general application. Here, we utilize the non-maximally entangled channels to implement two multiparty remote state preparation schemes for transmitting different quantum information from one sender to two receivers synchronously. The first scheme is adopted to transmit two different four-qubit cluster-type entangled states to two receivers with a certain probability. In order to improve success probabilities of such multicast remote state preparation using non-maximally entangled channels, we put forward the second scheme, which deals with the situation that is a synchronous transfer of an arbitrary single-qubit state and an arbitrary two-qubit state from one sender to two receivers. In particular, its success probability can reach 100% in principle, and independent of the entanglement degree of the shared non-maximally entangled channel. Notably, in the second scheme, the auxiliary particle is not required.

“…Fortunately, the evaluation of the average fidelity [8,9] is an efficient method to partially characterize the noise of quantum channels or gates. [10,11] The advantage of the average fidelity estimation method [12] is that it does not require large amounts of resources and is insensitive to state preparation and measurement errors (SPAM). [13] Randomized benchmarking [14][15][16][17][18][19][20][21][22][23] is an experimental scheme to measure the average fidelity.…”

We propose a method to estimate the average fidelity using the unitary 2t-design of a twirled noisy channel, which is suitable for large-scale quantum circuits. Compared with the unitary 2-design in randomized benchmarking, the unitary 2t-design for the twirling of noisy channels is more flexible in construction and can provide more information. In addition, we prove that the proposed method provides an efficient and reliable estimation of the average fidelity in benchmarking multistage quantum gates and estimating the weakly gate-and time-dependent noise. For time-dependent noise, we provide a scheme of moment superoperator to analyze the noise in different experiments. In particular, we give a lower bound on the average fidelity of a channel with imperfect implementation of benchmarking and state preparation and measurement errors (SPAM).

“…[8,9] Up to now, almost all of the studies on multi-party RSP and JRSP have been restricted to symmetric schemes where all receivers have equal power to reconstruct the target state sent by the sender or senders. [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] Recently, some hierarchical quantum communication schemes have been proposed, for example, hierarchical quantum in-formation splitting (HQIS), [25][26][27] hierarchical quantum secret sharing (HQSS), [28] and hierarchical dynamic quantum secret sharing (HDQSS). [29] In many practical scenarios, joint decision and hierarchial quantum communication are important.…”

Deterministic hierarchical joint remote state preparation with six-particle partially entangled state

et al. 2018

In this paper, we present a novel scheme for hierarchical joint remote state preparation (HJRSP) in a deterministic manner, where two senders can jointly and remotely prepare an arbitrary single-qubit at three receivers' port. A six-particle partially entangled state is pre-shared as the quantum channel. There is a hierarchy among the receivers concerning their powers to reconstruct the target state. Due to various unitary operations and projective measurements, the unit success probability can always be achieved irrespective of the parameters of the pre-shared partially entangled state.
