Quantum networking is a key element of quantum computation and quantum communication, it facilitates the transfer of information from one qubit to another. Griffith University are developing nodes for long-distance quantum networking based on entangled ion-photon qubits. Yb+ ions are trapped and manipulated by a microfabricated trap containing diffractive optics for high efficiency photon collection. A high resolution diffraction grating spectrometer is used to measure the qubit state from the entangled photons. A PPLN waveguide is under development for frequency conversion of the entangled UV photons to the telecommunication band for low-loss long-distance transmission through optical fibres. I present progress towards the goal of demonstrating long-distance qubit transfer between the Gold Coast and Nathan campuses via the optical fibre network.

About Physics Seminars

The weekly Physics Seminar series focuses on a broad range of physics research within SMP, along with frequent presentations from visiting researchers. Seminars are usually scheduled for 1.00pm on Tuesdays.

The talks are typically more specialised than a colloquium but are often attended by staff and PhD students across a broad range of areas. Speakers are thus encouraged to include introductory material in the talks.

All SMP researchers and HDR students are encouraged to speak. Please email Lewis Williamson to register your interest.

The seminars are open so there is no need to register your attendance.
