A study led by Trinity’s Dr Mark Mitchison has found that accurate timing is even more crucial to realising quantum computers than previously thought. Despite…

Trinity physicist Dr Mark Mitchison describes his research into quantum thermodynamics and the family inspiration behind his decision to become a scientist.

Prof Mark Mitchison is leading an EU quantum project, which aims to see if precision measurements can be made more energy efficient.

Currents were found to flow from cold to hot temperatures in some materials, described as ‘almost like watching a movie in reverse’.

Bruce Rolff/Alamy Keeping time accurately comes with a price. The maximum accuracy of a clock is directly related to how much disorder, or entropy, it creates every time it ticks. Natalia Ares at the University of Oxford and her colleagues made this discovery using a tiny clock with accuracy that can be controlled. The clock consisted of a 50-nanometre thick membrane of silicon nitride, vibrated by an electric current. Each time the membrane moved up and down once and then returned to its original position, the researchers counted a tick, and the regularity of the spacing between the ticks re...
