Did physicists create a wormhole in a quantum computer?

Physicists have used a quantum computer to generate an entity known as an emergent wormhole. Quantum systems can be linked by entanglement, even when separated by extremely long distances. The authors generated a highly entangled quantum state between the two halves of a quantum computer, creating an alternative description, known as a holographic dual, in the form of an emergent wormhole stretched between two exterior regions. They then simulated a message traversing this wormhole. Such exotic physics is part of efforts to reconcile quantum mechanics with the general theory of relativity.
