Markus Hanke Posted August 13, 2018 Share Posted August 13, 2018 There are three main concepts: 1. Granularity: physical observables can only take on discrete values 2. Indeterminacy: the outcome of measurements is stochastic in nature (unless of course the system has been prepared in a definite state) 3. Relationality: It is not meaningful to attribute properties to quantum systems, until such time when they are actually measured (lack of counterfactual definiteness) Link to comment Share on other sites More sharing options...

Also, wave particle duality is in a sense the same as quantum uncertainty. Wave-particle duality is the idea that a quantum object can behave like a wave, but that the wave behaviour disappears if you try to locate the object. (like in the double slit exp) The quantum uncertainty principle is the idea that it's impossible to know certain pairs of things about a quantum particle at once...like the exact position of a particle and its wave-behavior.https://arxiv.org/pdf/1403.4687.pdf Link to comment Share on other sites More sharing options...
