CQT eyes orbit for next experiment

CQT Principal Investigator Alexander Ling and Daniel Oi from the University of Strathclyde, UK, are collaborating to put an optical entanglement experiment into low Earth orbit. In this article, they describe the motivations and challenges.
Quantum theory has survived all challenges so far: the pioneering
experiments of Alain Aspect demonstrated quantum correlations
violating classical predictions, and experiments have tested quantum
entanglement – the “spooky action at a distance” that so disturbed Einstein – over ever greater separation. But these experiments have all been
Earth-bound. Isn’t it time to test quantum theory in space? Science is
driven by unexpected discoveries, discoveries often made at the limits of
our understanding or in extreme physical environments. Going into space
will stretch our tests of quantum theory, from observing entanglement
over even longer distances to exploring relativistic effects.
