A quantum-logic gate between distant quantum-network modules [PDF]
Science, 2021 Quantum gating at a distance The processing of quantum information is reliant on the encoding and manipulation of quantum states of a qubit. Superconducting circuits are the most advanced platform at present, but there is an issue with cross-talk between

Efficient Quantum Network Communication Using Optimized Entanglement Swapping Trees [PDF]
IEEE Transactions on Quantum Engineering, 2021 Quantum network communication is challenging, as the no-cloning theorem in the quantum regime makes many classical techniques inapplicable; in particular, the direct transmission of qubit states over long distances is infeasible due to unrecoverable ...

Asymmetric Quantum Multicast Network Coding: Asymmetric Optimal Cloning over Quantum Networks
Applied Sciences, 2022 Multicasting of quantum states is an essential feature of quantum internet. Since the noncloning theorem prohibits perfect cloning of an unknown quantum state, an appropriate protocol may depend on the purpose of the multicast.

Quantum Switchboard with Coupled-Cavity Array
Entropy, 2022 The ability to control the flow of quantum information is deterministically useful for scaling up quantum computation. In this paper, we demonstrate a controllable quantum switchboard which directs the teleportation protocol to one of two targets, fully ...
