Quantum optics with microwaves
- Physicists at ETH Zurich have demonstrated one of the quintessential effects of quantum optics – known as the Hong-Ou-Mandel effect – with microwaves, whose frequency is 100’000 times lower than that of visible light. The experiment takes quantum optics into a new frequency regime and could eventually lead to new technological applications.

Cream of the crop: sandwich chips
combining the best of two technologies.
Wolfgang Heinrich and Bernd Tillack are convinced of holding the key to faster and more powerful terahertz chips. The two scientists and their teams come from the Berlin-based Ferdinand-Braun-Institut (FBH) and from the IHP–Leibniz-Institut für innovative Mikroelektronik in Frankfurt/Oder – and thus from two different technology worlds.
