Wormholes

Teleporting people through space is still science fiction. But quantum teleportation is dramatically different and entirely real. In this episode, Janna Levin interviews the theoretical physicist John Preskill about teleporting bits and the promise of quantum technology.

Last fall, a team of physicists announced that they had teleported a qubit through a holographic wormhole in a quantum computer. Now another group suggests that’s not quite what happened.

The unprecedented experiment explores the possibility that space-time somehow emerges from quantum information.

In a landmark series of calculations, physicists have proved that black holes can shed information.

A proposal for building wormhole-connected black holes offers a way to probe the paradoxes of quantum information.

The renowned British physicist, who died at 76, left behind a riddle that could eventually lead his successors to the theory of quantum gravity.

Physicists theorize that a new “traversable” kind of wormhole could resolve a baffling paradox and rescue information that falls into black holes.

One of the world’s preeminent theoretical physicists seeks a quiet place to think.

A bold new idea aims to link two famously discordant descriptions of nature. In doing so, it may also reveal how space-time owes its existence to the spooky connections of quantum information.
