14:00 Keynote talk: Plasmonic Heterodyne Terahertz Receivers with Quantum-Level, Sensitivity at Room Temperature
Mona Jarrahi
UCLA (USA)
We introduce a terahertz receiver that uses plasmonic photomixing for frequency downconversion to offer quantum-level sensitivities at room temperature for the first time. Frequency downconversion is achieved by mixing terahertz radiation and a heterodyning optical beam with a terahertz beat frequency in a plasmonics-enhanced semiconductor active region. With a versatile design capable of broadband spectrometry, over a 0.1-5 THz bandwidth, we demonstrate receiver sensitivities down to 3 times the quantum-limit at room temperature.

14:30 Keynote talk: Quantum photonics using nanodiamonds and integrated optics
Christophe Couteau
University of Technology of Troyes UTT (France)
We will present our recent work on integrated quantum photonics based on a hybrid system made of colour centres in nanodiamonds and single photons within a common optical bus. This platform is a first step towards scalability for quantum communications. Ultimately, we aim to achieve entanglement via the interaction between two nodes thanks to a common photonics waveguide. We will present how we plan to control the positioning of nanodiamonds as well as the quantum optics properties of such emitters.
