Quantum networking of trapped-ion qubits
Lead Research Organisation:
University of Oxford
Department Name: Oxford Physics
Abstract
Demonstrate simple quantum algorithms across an elementary two-node quantum network. The key research questions are: whether entanglement can be obtained with sufficiently high fidelity across a quantum network for quantum information processing applications; whether entanglement can be purified across such a network; whether protocols such as "blind quantum computing" can be demonstrated. The student will use the UK's first quantum network apparatus to address these research questions, and build up new quantum engineering techniques such as dual-species quantum logic to enable the research.

| Description | The key objectives of the first stage of this award were to acheive high rate high fidelity entaglement between 2 ion trap nodes. We have recorded the best results by both these metrics compared to any other solid state system. Our final published results are 94% fidelity entanlement at a rate of 182 Hz. |
| Exploitation Route | The next stage is to try and increase the fidelity of this operation as in order to be useful for quantum computing operations we need to acheive higher than 99% fidelity. |
