> I argue that they can’t. In the physical world, continuous quantities (be they voltages or the parameters defining quantum-mechanical wave functions) can be neither measured nor manipulated exactly. That is, no continuously variable quantity can be made to have an exact value, including zero. To a mathematician, this might sound absurd, but this is the unquestionable reality of the world we live in, as any engineer knows.
Dyakonov‘s opinions have been rebutted by many prominent quantum information scientists and physicists. To put it charitably, his arguments don’t agree with the consensus. Check out [1] as an example criticism of his writing.
