'Quantum Cheshire Cat' becomes reality

By James Morgan

Scientists have for the first time separated a particle from one of its physical properties - creating a "quantum Cheshire Cat".

The phenomenon is named after the curious feline in Alice in Wonderland, who vanishes leaving only its grin.

Researchers took a beam of neutrons and separated them from their magnetic moment, like passengers and their baggage at airport security.

They describe their feat in Nature Communications.

The same separation trick could in principle be performed with any property of any quantum object, say researchers from Vienna University of Technology.
