Researchers entangle ions across a 230-meter quantum network

Trapped ions have previously only been entangled in one and the same laboratory. Now, teams led by Tracy Northup and Ben Lanyon from the University of Innsbruck have entangled two ions over a distance of 230 meters.

Emergent behavior observed in self-interacting light

Particles of light—photons—that are forced to interact with each other through specially structured glass demonstrate behavior evocative of the "fractional quantum Hall effect," a phenomenon that garnered the 1998 Nobel ...

Quantum cryptography: Making hacking futile

The Internet is teeming with highly sensitive information. Sophisticated encryption techniques generally ensure that such content cannot be intercepted and read. But in the future high-performance quantum computers could ...

Existing fiber optic cables can monitor whales

A new study demonstrates for the first time that the same undersea fiber optic cables used for internet and cable television can be repurposed to tune in to marine life at unprecedented scales, potentially transforming critical ...
