A quantum simulator for magnetic materials

Physicists understand perfectly well why a fridge magnet sticks to certain metallic surfaces. But there are more exotic forms of magnetism whose properties remain unclear, despite decades of intense research. An important ...

Making quantum encryption practical

One of the many promising applications of quantum mechanics in the information sciences is quantum key distribution (QKD), in which the counterintuitive behavior of quantum particles guarantees that no one can eavesdrop on ...

16 atomic ions simulate a quantum antiferromagnet

(Phys.org) —Frustration crops up throughout nature when conflicting constraints on a physical system compete with one another. The way nature resolves these conflicts often leads to exotic phases of matter that are poorly ...

Physicists create nanoscale spinning magnetic droplets

Researchers have successfully created a magnetic soliton – a nano-sized, spinning droplet that was first theorized 35 years ago. These solitons have implications for the creation of magnetic, spin-based computers.

Physicists use mechanical micro-drum used as quantum memory

JILA researchers demonstrated thatinformation encoded as a specific point in atraveling microwave signal—the vertical and horizontal positions of a wave pattern at a certain ime—can be transferred to the mechanical beat ...

Speeding algorithms by shrinking data

In computer science, the buzzword of the day is "big data." The proliferation of cheap, Internet-connected sensors—such as the GPS receivers, accelerometers and cameras in smartphones—has meant an explosion of information ...
