Google’s quantum computer simulation of a wormhole may not have worked

The first simulation of a wormhole on a quantum computer may not have been an correct illustration of a wormhole in spite of everything. Since the unique simulation was introduced final yr, one other group of researchers has examined the physics behind the work and located a number of issues that would scupper the outcomes.

At the centre of the unique work is a idea known as a “holographic wormhole”, which is a depiction of a wormhole that has been simplified utilizing methods from quantum mechanics to make it simpler to simulate. Importantly, …
