A recent paper published by Roger Colbeck and Renato Renner explores the possibility that the theory of quantum mechanics may not be the most accurate descriptor of real subatomic physics. They put it to the test, along with alternative theories, with the only requirement being that they are compatible with the idea of “free choice”. They find that quantum theory, of all the theories included, is the most “maximally informative” of all. This adds to the mounting evidence that although quantum mechanics deals mostly with probabilistic outcomes, it remains the most accurate descriptor of the quantum world thus far.
