Physicists Simulate a Simplified Wormhole on Google’s Quantum Computer
- nyc111 4y ago>> It’s important to point out, though, that the experiment comes with all kinds of caveats. The wormholes the group were simulating, and indeed, even the holographic principle on which they’re based, exist in a hypothetical kind of universe that operates very differently from our own. In addition, their experiments assumed only two dimensions: one spatial dimension and the dimension of time. >> “The relationship between quantum entanglement, spacetime, and quantum gravity is one of the most important questions in fundamental physics and an active area of theoretical research,” Spiropulu said. Experiment is done in two dimensions but the physicists describe an experiment which is valid in “spacetime" which must have 4 dimensions. It looks like there is a disconnect between theory and the experiment.
- sampo 4y ago> Experiment is done in two dimensions Not even that. They use the holographic principle (which itself is only a conjecture) to reduce dimensions. The actual experiment is done in 1-dimensional space-time: 1 time dimension and 0 space dimension. This 0-dimensional (0 space dimensions) hologram is supposed to describe events in the 1-dimensional space. But, again, they are not generating the 1-dimensional space in their actual experiment. They are generating the 0-dimensional model, which supposed to be a hologram of the 1-dimensional space.
