The Quantum Innovators workshop brings together the most promising young researchers in quantum physics and engineering. Guests are invited for a four-day workshop aimed at exploring the frontier of our field.
Perfect embezzlement of entanglement
Practical continuous variable quantum communication in fibre and free space systems
Christoph Marquardt, Max Planck Institute for the Science of Light
I will review our recent activities in continuous variable QKD that aims for the deployment of QKD equipment compatible with current telecom standards and research in satellite QKD that will make it possible to bridge long distances. In optical fibre systems continuous variable quantum cryptography reaches GHz speed and offers efficient integration with known telecommunication techniques, especially in short inner-city or data center links. Sending and receiving components, including quantum random number generators, can be efficiently built in integrated components. Optical free space communication is a reliable means to transmit classical and quantum information. Free space links offer ad-hoc establishment in intra-city communication, air-to-ground or satellite-to-ground scenarios.
