This looks like something exciting – not just because of the wonders that low-power magnetic computing could do to extend battery life of consumer devices, but because this is something possible in theory, that is now also possible in practice.
Sure, it's not a new field of computation – unlike quantum computing, which differs considerably from conventional computing – but it's potentially a major leap in energy efficiency for conventional computing.

Magnetic switches could use 10,000 times less power than silicon transistors | ExtremeTech
New research from UC Berkeley provides a proof of concept for a magnetic switch that could make computers thousands of times more energy-efficient, and provide some amazing new abilities, too.

Moving forward translates away from electron movement, to photon and/or wave movement, must be a slow news day
+Dolce Lattice That must be it! Thanks for refreshing my memory.
+Magnus Lewan I think you are thinking of magnetic core memory which was a bulky, high power, manually assembled array of torroidal ferrite beads strung into an array with fine wires which cris-crossed through them that could be magnetized either clockwise or counter-clockwise to accordingly represent binary digits. Used up through the mid 70s.

And I'm out of touch again. I thought magnetic switches was what computers in general used in the sixties and seventies, fifty years ago.
