'Spooky action at a distance' aboard the ISS
(Phys.org) —Albert Einstein famously described quantum entanglement as "spooky action at distance"; however, up until now experiments that examine this peculiar aspect of physics have been limited to relatively ...
'Metascreen' forms ultra-thin invisibility cloak
(Phys.org) —Up until now, the invisibility cloaks put forward by scientists have been fairly bulky contraptions – an obvious flaw for those interested in Harry Potter-style applications.
New scheme for quantum computing
