quantum theory

The Born rule bridges the math of quantum theory to the outcomes of experiments, which makes the field a legitimate scientific discipline in the first place.

“We want to bring it out of quantum theory and labs and take it to actual photons from stars,” Lau says.

The infamous and problematic "measurement postulate" of quantum theory is not needed, since quantum superpositions necessarily localise through their interaction with classical spacetime.

By connecting their new theory to quantum metrology, which uses quantum theory to make highly sensitive measurements, the Cambridge team has shown that entanglement can solve problems that otherwise seem impossible.

He had cracked the code of atomic structures, determining how atoms are modeled — electrons orbiting a nucleus of protons and neutrons — and helping create quantum theory in the process.
