Quantum network coding can effectively alleviate bottlenecks in quantum networks thus
improving the transmission efficiency and the throughput of the quantum network. Although …

Quantum network coding (QNC) aims at alleviating quantum communication congestion in
quantum networks. Although several QNC protocols have been presented, they cannot meet …

Hierarchical remote preparation of an arbitrary two-qubit state has not been investigated by
the previous work. We first put forward two deterministic schemes to realize the task among …

Quantum network coding with classical assistance can transmit quantum information with
fidelity one in error-free quantum channels. However, the dependency on classical network …

Cooperative communication is starting to attract substantial research attention in quantum
information theory. However, given a specific network, it is still unknown whether quantum …

In this paper, we propose a novel quantum network coding scheme to achieve the perfect
transmission of quantum states without loss of information. In our scheme, two pairs of non …

Multi-party quantum communication has gradually attracted widespread attention. To realize
the perfect transmission of quantum states among multiple participants, a novel multi-party …

We investigate bidirectional teleportation that works in a fair and efficient manner. Two
explicit protocols are proposed to realize bidirectional teleportation with a controller. One is …

We mainly consider quantum multi-unicast problem over directed acyclic network, where
each source wishes to transmit an independent message to its target via bottleneck channel …

In order to solve the information leakage caused by dishonest intermediate nodes in
quantum network coding, we apply quantum homomorphic encryption to the butterfly …
