Globally, four companies manufactured chips with 14 nanometre transistors in 2014, but in recent years they’ve struggled to continue shrinking the size of silicon transistors.

Last year scientists at FLEET published research in Nature revealing the discovery that the “topological” material sodium-bismuthide could be the key to achieving ultra-low energy electronics. Another two are taking a different tack, developing an entirely new quantum technology for computing which promises to enormously speed up, and improve the efficiency of, certain difficult computing tasks.
