The overarching aims of the QCUMbER project are to develop the experimental and theoretical tools required to address the quantum structure of the time-frequency degrees of freedom of ultrashort light pulses and to demonstrate their utility for new types of quantum technologies. The basis for this research direction is the recognition of the vast information capacity enabled by the quantum properties of spectral-temporal multimode states of light and their compatibility with integration and guided-wave distribution over optical fibres. We build upon the well-developed techniques of ultrafast optics, such as frequency combs, pulse shaping and metrology, to realize a long-term vision of massively entangled, controllable quantum states of ultrabroadband light pulses that open new vistas for fundamental science and engineering, in precision spectroscopy, clock synchronization, communications networks and ultimately computing.
To achieve the major goals of QCUMbER, five core research work packages (WPs) guide the project, which you can access on the left side of this page.
