The Tangled Tale of How Physicists Built A Groundbreaking Wormhole In A Lab

The wormhole theory postulates that a theoretical passage through space-time could create shortcuts for long journeys across the universe. Wormholes are predicted by the theory of general relativity. But be wary: wormholes bring with them the dangers of sudden collapse, high radiation and dangerous contact with exotic matter.

Wormholes were first conceived of by Albert Einstein and his fellow physicist Nathan Rosen in 1935, who argued that general relativity allowed for a ‘bridge’ between two black holes. At the same time, Einstein and Rosen, working with their colleague Boris Podolsky, questioned the quantum mechanics view of reality via a paradox that later researchers dubbed ‘entanglement’. These two ideas were brought together in 2013, when Leonard Susskind at Stanford and Juan Malcadena at Princeton argued that wormholes and entanglement are, in fact, the same thing. Three years later, Daniel Jafferis at Harvard and his graduate student Ping Gao proposed a way to traverse a wormhole. This idea was validated this year when a team of physicists led by Maria Spiropulu of the California Institute of Technology built a small-scale wormhole inside a quantum computer. Their experiment was a major breakthrough – the culmination of creative experimentation, emerging quantum computing technology and more than a century of speculation and research. And, as this short documentary from Quanta Magazine explores, in strengthening a link between black holes and quantum entanglement, it may have marked a massive step forward in the quest to bridge the worlds of general relativity and quantum mechanics.
