Robust Quantum Memory in a Trapped-Ion Quantum Network Node. [PDF]
Physical Review Letters, 2022 We integrate a long-lived memory qubit into a mixed-species trapped-ion quantum network node. Ion-photon entanglement first generated with a network qubit in ^{88}Sr^{+} is transferred to ^{43}Ca^{+} with 0.977(7) fidelity, and mapped to a robust memory ...

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 ...

Aggregating Quantum Networks [PDF]
OSA Advanced Photonics Congress 2021, 2020 The implementation of quantum error-correction codes needs high efficiency transmission channels and significant physical resources. Here we show that aggregating quantum networks alleviate those issues when applied to the quantum Reed-Salomon code.
