T1.1 High-speed Room-temperature Control of Quantum Emitters with Plasmonic Nanostructures
Simeon I. Bogdanov (Purdue University)
Quantum technologies simultaneously require accurate control over elementary quantum systems and robust protection from interactions with their environment. Single photons are arguably the best candidates for realizing quantum networks thanks to their fast propagation speed and low decoherence rates. However, the fast production of single photons and deterministic interactions between them are difficult to achieve because of photons’ relatively weak coupling with matter. As a result, most of today’s long-range photonic quantum networks still operate at kHz bitrates, while photonic quantum information processing is limited to systems consisting of about ten photons. Enhancing light-matter interaction is possible using dielectric resonators but the speed of the resulting devices will be eventually limited by the high-quality factors. Plasmonic metal-based nanostructures used along with the conventional dielectric photonic circuitry allow a targeted and strong enhancement of light-matter interaction in a broad wavelength range. This approach promises bitrates up to the THz range and room-temperature operation of quantum optical components. I will outline present and future directions in the development of a platform for room-temperature high-speed integrated quantum photonics, including the application of machine learning techniques for quantum optical measurements.
