Quantum physicists in the Netherlands, Spain, and the UK have confirmed in the lab that the weird instant correlations between remote “entangled” particles are real. The question that comes to mind is, can quantum weirdness be used to send instant message across space-time, faster than light?
The new experimental conformation of instant entanglement – not the first, but the strongest to date – is published on arXiv with the title “Experimental loophole-free violation of a Bell inequality using entangled electron spins separated by 1.3 km.” See also my summary and Zeeya Merali’s summaries published at Foundational Questions Institute (FQXi) website and Nature News.
The researchers measured the spins of hundred of entangled particles in two University of Delft labs, located 1.3 km apart, and confirmed that the entangled correlations are still observed when there is not enough time for light to travel from the first lab to the second, which means that entanglement isn’t limited by the speed of light.
If the correlations between entangled particles aren’t limited by the speed of light, is it possible to send instant messages faster than light (FTL), or across time, or do even weirder forms of quantum magic?
