600-year-old starlight addressed a loophole in quantum theory

Share

Quantum entanglement, where two particles are separated by space and yet inextricably linked by the laws of quantum mechanics, has already been proven to be real, but something called the freedom-of-choice loophole has so far made it impossible to definitively prove the theory. That is, until physicists from the University of Vienna and MIT addressed that loophole with a blast of 600-year-old starlight.
If two particles are entangled, then any measurement made on one of them …
