For building quantum computers, making use of both electronics and photonics – technology that works with light – on one and the same chip, is promising. Thanks to silicon technology that we know well from today’s electronic devices, quantum devices could be better protected from influences from the outside world. Another advantage is that they can be scaled up to larger systems. Unfortunately, light and silicon are not the best friends. That is, unless you add germanium to it, in a fully new hexagonal crystal structure.
Hydrogen technology company H2Site has raised 12.5 million euros in a Series A funding round led by Breakthrough Energy Ventures (BEV). The funding is to accelerate the scale up of the company’s integrated membrane reactor and membrane separation technologies.
