Distributed Quantum Computing Using A Trapped-Ion Quantum Network
In this talk, I will give an introduction to the ideas of quantum networking using trapped ions and describe experimental progress in the Oxford group. Our elementary two-node setup combines "network" qubits, which can be remotely entangled via an optical fibre link, with long-lived memory qubits. Recent work includes demonstrations of distributed gates and algorithms and the generation of multi-particle entangled states, over the network link.
About the Speaker
Professor David Lucas is an experimental atomic physicist at Oxford whose research focuses on trapped‐ion quantum computing. He leads a group working on precision control, coherence, and error reduction in ion trap qubits, pushing toward fault-tolerant quantum logic. Recently his team set a new global benchmark for single-qubit gate fidelity — achieving an error rate of just 0.000015% (one in 6.7 million) — and has demonstrated distributed quantum computation by linking remote ion processors via photonic interfaces.
