Nanoscale Quantum Photonics Laboratory

Quantum technologies are expected to make important developments in various fields of engineering including computing, sensing, metrology, and communication. Since quantum effects become more evident and more robust as the system scales down, devices with atomically precise elements could provide a route for quantum technologies operating at elevated temperatures. Our research focuses on the optical properties of nanomaterials and the physics of nanoscale photonic devices, investigating new approaches for utilizing their quantum properties. By engineering atomically defined nanostructures and integrating them into nanoscale devices, we explore novel concepts in photonics for future quantum technologies.

Optoelectronic devices harness the interactions between electrons and photons and are widely used in everyday applications, for example solar cells and light-emitting diodes. Continued advances in device fabrication techniques have enabled the integration of individual nanomaterials into device structures, providing opportunities to utilize the quantum nature of photons. Our research focuses on pioneering and engineering next-generation nanodevices that exploit the quantum properties of nanomaterials and enable control of light at the quantum level. By combining state-of-the-art nanofabrication and nanosynthesis techniques, we investigate devices capable of manipulating single photons in the telecommunication band and integrated photonics for quantum applications at room temperature.
