Computers were once the size of large rooms. This changed when physicists came to understand a new state of matter: the semiconductor. From that point on, we learnt to grow computers from crystals of silicon.

These days the race is on to build a practical quantum computer. These are again the size of large rooms. What we need is a silicon for the 21st century featuring a new quantum state of matter.

Theoretical physicist Felix Flicker returns to the Ri to discuss discuss some possible candidates for these quantum crystals, including a naturally occurring mineral which features some (but not all) of the necessary properties.
