American quantum computing startup PsiQuantum announced that it has solved a major challenge in making quantum technology practical: producing quantum chips in large quantities.
PsiQuantum emerged from "stealth mode" in 2021 with a major funding announcement, followed by two more in the previous year.
The company specializes in "photonic" quantum computing, a method that has long been considered impractical. This approach encodes data in individual particles of light, offering several key benefits, such as low noise, high-speed operation, and seamless integration with existing fibre-optic networks. However, it has faced significant hurdles, including the extreme hardware demands needed to manage photons' high speed, their tendency to get lost, and difficulties in creating and detecting them.
If PsiQuantum’s technology delivers on its promise, it could mark the beginning of quantum computing’s first truly scalable era

Now, PsiQuantum claims to have overcome many of these challenges. In a new peer-reviewed paper published in Nature, the company revealed hardware for photonic quantum computing that can be produced in large quantities, solving the issue of scaling up the system.
