The Integrated Optical Platform research at CQC²T focuses on the integration and scalability of quantum optics. The goal of this research is to realize the technological infrastructure for large scale integrated optical devices with a computational complexity to outperform current classical computers.
With our technology we developing devices for the generation of nonclassical state of light, such as single photons and squeezed vacuum, their manipulation, and detection all on a single chip. The key element of such devices is the optical waveguide, a channel that guides light through the optical chip.
Waveguides can be fabricated using different processes and materials. Within CQC²T we are developing an integrated optical quantum computing platform based on a material called lithium niobate (LN). As a leading material in the photonics industry, LN has several important properties that make it attractive for realising quantum computing applications, including low propagation losses, high nonlinearity, and fast electro-optical reconfigurability.
One of the main goals of our research on this platform is to realise measurement-based quantum computation using continuous variables.
