| Project Detail |
The prospect of a “Quantum Internet” interconnecting quantum computers & sensors via quantum information networks (QINs) promises to enable new technological & societal breakthroughs. Quantum “entanglement” between pairs of particles enables the prospect of absolutely-secure communications and distributed quantum computing within the QIN. However, quantum principles render classical techniques for extending range inapplicable. A Quantum Internet thus requires an efficient means of enabling reliable quantum links. QMLINK builds upon our team’s work within the EU Flagship Quantum Internet Alliance (QIA) project in developing a quantum memory (QM) based upon laser-cooled ensembles of cold atoms and quantum networking protocols leveraging this technology. Welinq’s QM, with a world record 90% storage efficiency, makes quantum interconnection possible. Our ambitious project goal is to develop the world’s first industry-grade QM links for QINs combining high-efficiency & long storage time with integrated frequency conversion for interfacing with optical telecommunication bands. Welinq’s QM addresses the critical need for quantum repeaters essential for secure, fast communication at long distances. We have a well-defined plan to achieve TRL6, while attaining storage times at least an order of magnitude beyond state-of-the-art for high-efficiency QM, which will greatly increase the maximal ranges & capabilities of QINs. We will integrate our QM link solution in the QIN test-bed deployed throughout the Paris region (ParisRegionQCI) to demonstrate our system at a TRL6 level, showcase our product to potential customers & key QIN industry players, and gain invaluable insight towards realizing the Quantum Internet. EIC support will accelerate our translation of cutting-edge research into industrial products critical to European quantum sovereignty, advancing towards applications of our QM in distributed quantum computing, while creating high-quality jobs for a digital Europe. |
