The challenge of finding a sustainable path to continuing the IT revolution is critical, and time is running out. I can tell you today with reasonable certainty that Moore’s Law will be declared dead within the seven-year operation of the Centre–perhaps even before our mid-term review! Computer chips will cease to gain in efficiency, and yet our demand for computation …
The information technology revolution has improved our lives, and we want it to continue. For example, our smartphone has become one of the most important devices of our everyday life: we use it to access up-to-date weather predictions, to plot the best route through traffic, and to watch the new series of House of Cards. And we expect it be …
Our insatiable appetite for computing means ITC already consumes 5–8% of global electricity, and is doubling each decade.

Quantum batteries also offer potential for vastly better thermodynamic efficiency, and ultra-fast charging time. The study, which was co-led by …
Wait. What do you mean ‘transistors’? Yep, ‘transistors’ are still the basis of electronics. In essence, they’re the tiny controllable switches that form the building blocks of logic circuits, switching between open (0) and closed (1). In your Dad’s old ‘wireless’ radio, transistors were the small metallic components shaped like War of the Worlds war tripods. Those replaced the glass …
