This is a **theatre** and **livestream** talk from the **Royal Institution of Great Britain.** What could replace silicon in the quantum age? Theoretical physicist **Felix Flicker** explores the remarkable materials powering tomorrow's computers. **ADVANCE BOOKING AND PAYMENT IS REQUIRED FOR THIS TALK.** **More details and booking instructions on the RI web site:** **[https://www.rigb.org/whats-on/how-grow-quantum-computer](https://www.rigb.org/whats-on/how-grow-quantum-computer)** **SUMMARY** 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 some possible candidates for these quantum crystals, including a naturally occurring mineral which features some (but not all) of the necessary properties. Copies of Felix's book "[The Magick of Matter: Crystals, Chaos and the Wizardry of Physics](https://geni.us/wJYFBl)" are available from here. Please note copies of the book will not be available to purchase at the Ri. This is a **theatre** and **livestream** event for an adult audience, where the speakers and audience in our Theatre are joined by our audience online. **The livestream will go live around 6.55pm, and the talk will begin at 7.00pm. If you register but miss the livestream, the video will be available to you via the same link for two weeks after the event date.** For more information on livestreams, see the information below, or [visit our FAQs page](https://www.rigb.org/whats/faqs-ri-livestreams).
