Physicists double their teleportation power

Quantum technique transfers two photon properties

The bandwidth for quantum teleportation has doubled. A new technique transfers information about one particle so that another particle takes on two, rather than just one, of the original particle’s quantum properties.

Chinese researchers accomplished the feat by nesting one quantum teleportation apparatus inside another. “It’s impressive,” says Wolfgang Tittel, a quantum physicist at the University of Calgary in Canada. “It’s conceptually very simple but technically very difficult.”

The achievement, reported in the Feb. 26 Nature, does not bring scientists much closer to teleporting pens, puppies or people à la Star Trek. But teleporting multiple properties over large distances would enhance proposed quantum communication networks that rely on encoding information in particles’ delicate quantum properties.

The Chinese team, led by Jian-Wei Pan and
