Quantum Teleportation Was Just Achieved With 90% Accuracy Over a 44km Distance

Scientists are edging closer to making a super-secure, super-fast quantum internet possible: they’ve now been able to ‘teleport’ high-fidelity quantum information over a total distance of 44 kilometres (27 miles). Both data fidelity and transfer distance are crucial when it comes to building a real, working quantum internet, and making progress in either of these […]

The Year’s Biggest Breakthroughs in Physics This year, two teams of physicists made profound progress on ideas that could bring about the next revolution in physics. Another still has identified the source of a long-standing cosmic mystery. 1. Here’s an extremely brief version of the black hole information paradox: Stuff falls into a black hole. […]

Quantum reality is either weirdly different or it collapses | Ars Technica

Quantum mechanics, when examined closely, poses some deep questions about reality. These questions often take the form of thought experiments, which are later (usually much later) followed up by real experiments. One of the most difficult and deepest of these is a thought experiment proposed by Eugene Wigner in the 1960s, called “Wigner’s friend” (you […]

Scientists discover way to make quantum states last 10,000 times longer

If we can harness it, quantum technology promises fantastic new possibilities. But first, scientists need to coax quantum systems to stay yoked for longer than a few millionths of a second. A team of scientists at the University of Chicago’s Pritzker School of Molecular Engineering announced the discovery of a simple modification that allows quantum systems to […]
