New quantum paradox reveals contradiction between widely held beliefs – Phys.org

Quantum physicists at Griffith University have unveiled a new paradox that says, when it comes to certain long-held beliefs about nature, “something’s gotta give.”
Quantum theory is practically perfect at predicting the behavior we observe when we perform experiments on tiny objects like atoms. But applying quantum theory at scales much larger than atoms, in particular to observers who make the measurements, raises difficult conceptual issues.
In a paper published in Nature Physics, an interna…
