Observing the Rosensweig instability of a quantum ferrofluid

Whoa! Paul Rudd takes on Stephen Hawking in quantum chess – with Keanu Reeves voiceover
Strange things may be afoot at the Circle-K, but they don’t compare to what’s going on in a new video featuring the narration of Keanu Reeves in which actor Paul Rudd challenges physicist Stephen Hawking to a game of quantum chess. The video, directed...
‘House of Cards’ star Kevin Spacey: Virtual reality will be a ‘quantum leap forward for storytellers’
LAS VEGAS— A little bit of Johnny Carson, Bill Clinton and Frank Underwood showed up Monday at the AT&T 2016 Developer Summit. Nah, not really. It was just Academy Award-winning...
Quantum superposition at the half-metre scale
The quantum superposition principle allows massive particles to be delocalized over distant positions. Though quantum mechanics has proved adept at describing the microscopic world, quantum superposition runs counter to intuitive conceptions of reality and locality when extended to the macroscopic scale, as exemplified by the thought experiment of Schrödinger’s cat. Matter-wave interferometers, which split and recombine wave packets in order to observe interference, provide...

Hybrid quantum logic and a test of Bell’s inequality using two different atomic isotopes
Entanglement is one of the most fundamental properties of quantum mechanics, and is the key resource for quantum information processing (QIP). Bipartite entangled states of identical particles have been generated and studied in several experiments, and post-selected or heralded entangled states involving pairs of photons, single photons and single atoms, or different nuclei in the solid state, have also been produced. Here we use...
Quantum physics: Entanglement beyond identical ions
Control of quantum particles has been extended to enable different types of ion to be entangled — correlated in a non-classical way. This opens up opportunities for the development of new quantum technologies. See Letters p.380 & p.384
