Don't underestimate the importance of this discovery if implemented it will make a HUGE breakthrough in the computer processor development (over time). If this is validated and developped it means a completely new computer processor revolution in say 15 years time, similar to what current technology has done for us.
Binary would never be the same with 0 and 1, but with quantum bits it can do both:
A team of scientists at the MPQ realizes a first elementary quantum network based on interfaces between single atoms and photons. Whether it comes to phoning a friend or to using the internet
