The existence of time crystals – a particularly fascinating state of matter – was confirmed only a few short years ago, but physicists have already made a pretty big breakthrough: they have induced an interaction and observed between two time crystals. In a superfluid helium-3, crystals exchange quasi-particles twice without …

One of the main challenges in turning quantum technology from potential to reality is getting superfine quantum states to last longer than a few milliseconds – and scientists are simply lifting the bar by a factor of about 10,000. They did this by tackling what is called decoherence: that is, …
