Quantum teleportation over 16 km in open air

Quantum teleportation is not the easiest concept to understand, much less believe. Teleportation sounds like something out of Star Trek. It’s not; this is real. In what promises to be a milestone experiment led by Jian-Wei Pan and Cheng-Zhi Peng at the University of Science and Technology of China and Tsinghua University (Beijing, China), quantum [...]

Is it goodbye to “Primordial soup?”

Over the years how many times have you encountered the term ‘primordial soup’ to explain the ferment in which life originated on Earth? The idea of a kind of organic broth in Earth’s early waters, struck by lightning, ultraviolet light, or some other catalyst, and producing slowly but surely the various compounds that eventually take [...]

A big step up: Two qubit computing

Step by step we’re moving closer to useful quantum computing. A big step, announced by the National Institute of Standards and Technology (NIST, USA), was the demonstration of a computing device using two qubits. Previous demonstrations by various researchers have used one qubit. In computing, two computational units are far more powerful than one. This [...]
