PsiQuantum Plans Light-Based Quantum Computer

PsiQuantum, founded in 2016 by four physicists from UK universities, is developing a quantum computer designed to utilize light particles. This machine, intended to be housed in a facility resembling a data center and ice cream factory, will contain approximately 100 stainless-steel cabinets. Each cabinet will hold hundreds of chips where thousands of light particles will travel through a complex network of optical switches and beam splitters. The precise measurement of each photon's path is crucial for solving complex problems that could take conventional computers millions of years. The company's objective is to be the first to successfully construct a functional quantum machine, positioning itself within a competitive landscape of organizations pursuing similar ambitious goals.

In parallel, a separate engineering feat involves the construction of what will soon be the world's longest and deepest subsea road tunnel. Located beneath the North Sea, this 16.6-mile tunnel will reach a depth of 1,280 feet at its deepest point. The project aims to demonstrate that significant engineering accomplishments are still achievable, even in times when progress can feel challenging. This narrative is part of an MIT Technology Review Narrated podcast series, published weekly on Spotify and Apple Podcasts, highlighting ambitious engineering projects.
