I derive the quantum mechanical prediction −a⋅b for the singlet spin state using local measurement functions within the Space ...

Quantum coherence underpins the ability of light to exhibit wave-like interference effects and to maintain fixed phase relationships across spatial and temporal degrees of freedom. In quantum optics, ...

But after reading Decoherence and Quantum Darwinism, a book published in March 2025 by the physicist Wojciech Zurek, I’m excited by the possibility of an answer that does away with all those fanciful ...
