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

The famous cat-in-a-box thought experiment by Austrian physicist Erwin Schrödinger is an illustration of one of the defining characteristics of quantum mechanics – the unpredictable behaviour of particles at the quantum level.   It makes working with quantum systems incredibly difficult; but what if we could make quantum predictions? A team of physicists believes it’s

Scientists have found evidence that a fundamental physical constant used to measure electromagnetism between charged particles can in fact be rather inconstant, according to measurements taken from a quasar some 13 billion light-years away.   Electromagnetism is one of the four fundamental forces that knit everything in our Universe together, alongside gravity, weak nuclear force,

Eight years after he first shared it online, Kyoto University mathematician Shinichi Mochizuki’s controversial, 600-page proof for a profound mathematical conjecture has been approved for publication in an academic journal.   But there’s a twist: academic mathematicians around the world didn’t believe that Mochizuki solved the problem, known as the “abc conjecture,” back then, Nature

Well, those crazy chemistry cats have done it. Nearly 200 years after the molecule was discovered by Michael Faraday, researchers have finally revealed the complex electronic structure of benzene.   This not only settles a debate that has been raging since the 1930s, this step has important implications for the future development of opto-electronic materials,

Scientists have used super high-speed cameras to capture the moment liquid droplets combine together, providing a unique, preternatural glimpse of fluid dynamics the human eye can’t observe on its own.   Using an experimental setup involving two synchronised high-speed cameras – one shooting from the side, and the other looking upwards (courtesy of a mirror

Scientists have managed to get two quantum memories entangled over 50 kilometres (31 miles) of fibre optic cables, almost 40 times the previous record. This achievement makes the idea of a super-fast, super-secure quantum internet a much more plausible one.   Quantum communication relies on quantum entanglement, or what Einstein called ‘spooky action at a distance’:
