Optical setups have pioneered many of the fundamental test of quantum mechanics, and are still at the forefront of research on quantum information and metrology, mainly thanks to their robustness to decoherence. While it is clear optics will play a major role in real-world implementation of quantum technologies, as other systems scalability remains one of the major issues.
Here we will present how one can benefit from the highly multimode nature of ultrafast trains of optical pulses (optical frequency combs) to handle a large number of quantum modes and implement quantum information protocols. The combination of continuous variable quantum optics approach with the technologies available around ultrafast optics allows for very promising approach to both quantum metrology and measurement based quantum computing. We will address both practical experimental implementation along with theoretical consideration on the prospects of quantum information processing with light.
