One Very Cool Cat!

Here's a little news items from Nature magazine that I thought was very cool:


Photonic Schroedinger cat breaks record

Physicists in China, Austria and Germany claim to have created the
largest ever photonic "Schroedinger cat", a popularized term given to
entangled particles that are in a superposition of two quantum states.
The physicists also claim their apparatus can create a six-photon
"cluster" state, which could bring the physical realization of a quantum
computer one step closer.
