Quantum theorem deals fatal blow to Einstein's view of reality, physicists say
The PBR theorem, published in 2012, has convinced many theorists that the universe is fundamentally stranger than common sense suggests.
A quantum theorem first published in 2012, known as PBR, has convinced many theorists that quantum mechanics rules out the most commonsense understanding of reality. Under its assumptions, the theorem rules out the idea that the quantum state merely represents incomplete knowledge of an underlying real world.
