Diamonds are a researcher’s best friend


A fundamentally secure and private internet connection? That is exactly what Sophie Hermans from QuTech is working on. Recently, she and her colleagues have reached a new milestone on the way to the quantum internet – by using diamonds.

If you use online banking, or send a confidential email to your boss, it goes without saying that you don’t want anyone else to read along. With a quantum internet you can use a connection which is fundamentally secure, no one would be able to listen in unnoticed.

But a quantum internet can do more. “By using a quantum internet you can link multiple quantum computers and combine their computational power. You can perform calculations in the cloud, for instance to develop new medicines, and it is possible to do so with full privacy. Things that are impossible nowadays” says Sophie.
