Physicists have finally observed a quantum interaction between a group of four entangled electrons. Until now, this interaction was purely theoretical, but now it’s been caught in action by cleverly cooling a superconducting crystal and stressing it under high pressure. The results of this exciting experiment are now opening doors to further refining our knowledge

Chinese scientists have successfully sent information between entangled particles through sea water, the first time this type of quantum communication has been achieved underwater. In this proof-of-concept experiment, information was sent across a 3.3-metre (10.8-foot) long tank of seawater, but the researchers predict they should be able to use the same technique to send unhackable

Electrons have been caught flowing through graphene like a liquid, reaching limits physicists thought were fundamentally impossible. This type of conductance is known as ‘superballistic’ flow, and this new experiment suggests it could revolutionise the way we conduct electricity. If that’s not crazy enough, the super-fast flows actually occur as a result of electrons bouncing

Since the discovery of graphene in 2004, there’s been a proliferation of strange new two-dimensional materials. In all of them, scientists have been chasing one invaluable property – magnetism, which is crucial for data storage, medical devices, and electricity generators. After years of searching, many suspected that true two-dimensional magnets might not actually exist. But

For the first time, physicists have demonstrated that a universe like ours with three spatial dimensions could actually host a naked singularity – an event so intense, the laws of physics would fall apart. Until now, researchers have only been able to place naked singularities in five-dimensional universes, but by proving that they could theoretically

Researchers have constructed the world’s thinnest metallic nanowire, creating a stable string of the chemical element tellurium, that measures just one atom thick. The team behind the nanowire says the material is the most precisely configured ‘one-dimensional‘ system yet, and the technique used to produce the one-atom-thick atomic chain could lead to new advances in

The first direct detection of gravitational waves, a phenomenon predicted by Einstein’s 1915 general theory of relativity, was reported by scientists in 2016. Armed with this “discovery of the century”, physicists around the world have been planning new and better detectors of gravitational waves. Physicist Professor Chunnong Zhao and his recent PhD students Haixing Miao
