What quantum computers may tell us about quantum mechanics
... Quantum mechanics occupies a unique position in the history of science. It has survived all experimental tests to date, culminating with the most precise comparison of any measurement to any theory – a 1987 measurement of the electron’s magnetic moment, or gyromagnetic ratio ge = 2.00231930439 (Van ...
