A holographic wormhole in a quantum computerDr. Quantum Supremacy responds:
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.
Tonight, David Nirenberg, Director of the IAS and a medieval historian, gave an after-dinner speech to our workshop, centered around how auspicious it was that the workshop was being held a mere week after the momentous announcement of a holographic wormhole on a microchip (!!) — a feat that experts were calling the first-ever laboratory investigation of quantum gravity, and a new frontier for experimental physics itself. Nirenberg asked whether, a century from now, people might look back on the wormhole achievement as today we look back on Eddington’s 1919 eclipse observations providing the evidence for general relativity.That 1919 eclipse was hyped with a NY Times headline: “Men of Science More or Less Agog Over Results of Eclipse Observations”.
I confess: this was the first time I felt visceral anger, rather than mere bemusement, over this wormhole affair. Before, I had implicitly assumed: no one was actually hoodwinked by this. No one really, literally believed that this little 9-qubit simulation opened up a wormhole, or helped prove the holographic nature of the real universe, or anything like that. I was wrong.
Update: Here is the Quanta video.
Almost a century ago, Albert Einstein realized that the equations of general relativity could produce wormholes. But it would take a number of theoretical leaps and a “crazy” team of experimentalists to build one on Google's quantum computer.
