Trapped ions are among the most promising candidates for quantum computing platforms. Quantum information can be encoded in ions’ electronic states, where it can be processed with high-fidelity gate operations and read out deterministically. An outstanding challenge in the field — not only for ion-trap computers, but for all experimental realizations — is how to link together remote quantum computers. Such quantum networks would enable distributed quantum computing as well as secure communication over quantum channels.
By coupling an ion to the mode of an optical cavity, we can construct an interface between single ions and single photons. This interface allows us to transfer quantum information from ions onto photons for long-distance distribution over optical channels. I will discuss probabilistic and deterministic approaches to ion-photon quantum networks in our research group, based on ion-photon entanglement and ion-photon state transfer. Furthermore, I will discuss work in progress to link ions in distant cavities.
All are welcome to attend. Join us for light refreshments at 3:30 pm in PHY 153.
The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
