Hippie days: How a handful of countercultural scientists changed the course of physics in the 1970s
Every Friday afternoon for several years in the 1970s, a group of underemployed quantum physicists met at Lawrence Berkeley Laboratory, in Northern California, to talk about a subject so peculiar it was rarely ...
'Quantum magic' without any 'spooky action at a distance'
The quantum mechanical entanglement is at the heart of the famous quantum teleportation experiment and was referred to by Albert Einstein as "spooky action at a distance". A team of researchers led by Anton ...
