Monolithic generation & detection of squeezed light in silicon nitride photonics (Mono-Squeeze)
Lead Research Organisation:
University of Bristol
Department Name: Physics
Abstract
Applications of squeezed light span quantum technologies, including sensing, communications and computing. Integrated photonics provides scale-up, miniaturisation and increased robustness of optical devices, and various material platforms are being explored for photonic technologies that harness quantum phenomena, including squeezed light. This is due to the phase stability provided for phase sensitive quantum photonic components, such as homodyne detection. However, there is currently no approach to integrate squeezed light generation and quantum light detection into one chip. This project will engineer a scalable and manufacturable integrated photonics platform that generates, manipulates and measures squeezed quantum states of light in one monolithic chip architecture - silicon nitride nano-photonics. This will simplify assembly, miniaturise footprint, and enhance robustness of components for: quantum sensing, quantum communications and continuous variables quantum computing.

| Results and Impact | We hosted a group of A-level students from around the UK to visit our labs, take part in workshops and experiments set up by members from our wider department that included members of this research team. Members from this research team directly engaged with the audience in a lab demonstration session. This event (Quantum in the Summer) has been running in our department since 2015, and during the recruitment for the recent intake of postgraduate students in our department we have received applications from students that had previously attended this event. |
