"We could be within 5 years of really falsifying Einstein's classical theory."
How? By generating entanglement in an experiment to test quantum gravity!
I'm excited to release a technical deep-dive into how to test quantum features of gravity, explained in an approachable and intuitive way by Prof Vlatko Vedral from the University of Oxford.
We go right from Feynman's original thought experiment about putting a single mass in superposition, to Vlatko and his collaborators' Chiara Marletto & Sougato Bose's recent "BMV" two-mass experimental proposal.
As well as carefully explaining what different scenarios and results tell us about the nature of quantum gravity, Vlatko outlines actual experimental requirements and progress towards implementing this crucial test in the near future.
