Keeping qubits stable – those quantum equivalents of classic computing bits – will be key to realising the potential of quantum computing. Now scientists have found a new obstacle to this stability: natural radiation. Natural or background radiation comes from all sorts of sources, both natural and artificial. Cosmic rays contribute to natural radiation, for

The existence of time crystals – a particularly fascinating state of matter – was only confirmed a few short years ago, but physicists have already made a pretty major breakthrough: they have induced and observed an interaction between two time crystals. In a helium-3 superfluid, two time crystals exchanged quasiparticles without disrupting their coherence; an

One of the major challenges in turning quantum technology from potential to reality is getting super-delicate quantum states to last longer than a few milliseconds – and scientists just raised the bar by a factor of about 10,000. They did it by tackling something called decoherence: that’s the disruption from surrounding noise caused by vibrations, fluctuations

When an enormous explosion created a mushroom cloud over Beirut, killing dozens of people and injuring thousands more, online commentators and conspiracy theorists quickly jumped to a frightening claim: A nuclear bomb had gone off in Lebanon’s capital city. But as state officials say, and contrary to those fast-spreading rumours, the explosion was almost certainly not caused

Longer-lasting, more efficient batteries would be a boost for everything from smartphones to electric vehicles, and scientists have now made an unexpected discovery that could help develop next-gen battery tech, as well as faster catalysts and other advanced materials. An analysis of the very earliest stages of lithium battery charging – known as nucleation –

Nearly a century after experiments confirmed that atoms, matter’s smallest building blocks, have ethereal, wave-like characteristics, physicists have just found a new way to show how mammoth-sized molecules ripple with the same uncertainty. Researchers from the University of Vienna and the University of Duisburg-Essen, Germany, put a new spin on a classic experiment to create

In the strange field of quantum physics, quantum entanglement – what Einstein called “spooky action at a distance” – stands out as one of the most intriguing phenomena. And now scientists just managed to successfully demonstrate it again, this time onboard a CubeSat satellite orbiting Earth. Quantum entanglement is where two particles become inextricably linked
