France-based, Welinq is a quantum computer startup, specifically focused on “quantum memory” . Welinq’s quantum memory interconnects facilitate the storage & on-demand release of quantum info. They work by leveraging laser-cooled neutral atom technology that has demonstrated 90% efficiency in storage & retrieval. This enables to scale-up quantum computers (by entangling physically separated quantum processing units), short-cutting error correction (by redundantly encoding quantum info on many physical qubits), the deployment of QPUs on premise, in the cloud & quantum information networks. (Ps: another Paris-headquartered startup betting on neutral atoms is Pasqal, which we covered here). Welinq was founded in 2022 by Tom Darras (CEO), Jean Lautier-Gaud (CCO), Julien Laurant (Scientific Advisor) & Eleni Diamanti (Scientific...

UK-based Unwasted has developed “Neverwaste”, a process that refines & modifies the fibers inside waste cardboard (made from virgin & recycled timber), to produce a panel board that can be used across construction, flooring & furniture. The process does not use any glues, resins or other harmful chemicals, but instead a “continuous pressing & dying cycle”. One thing's for sure, Unwasted taps into a cheap & abundant feedstock (for the foreseeable future): the average UK household discards 13,000 different pieces of carboard annually; cardboard (as well as paper) accounts for 41% of the world’s solid waste (a trend amplified by the rise of e-commerce) - with a large portion burned or dumped in landfills....
