May 28, 2018 (Phys.org) -- In the popular movie franchise "Back to the Future," an eccentric scientist creates a time machine that runs on a flux capacitor.
Now a group of actual physicists from Australia and Switzerland have proposed a device that uses the quantum tunneling of magnetic flux around a capacitor, breaking time-reversal symmetry.
The research, published this week in Physical Review Letters, proposes a new generation of electronic circulators, which are devices that control the direction in which microwave signals move.
It represents a collaboration between two Australian Research Council Centres of Excellence: the Centre for Engineered Quantum Systems (EQUS) and the Centre for Future Low-Energy Electronics Technologies (FLEET).
