See more at physics Examples of quantum physicsquantum physics In quantumphysics, we do not even have a 'physical object' without measurement and mathematics. However, if one's aim is to explain the origins of the universe, the model is limited and requires the use of quantumphysics. A key feature of quantumphysics is the role of measurement. Yet the concept of computational power provides a fundamentally new language for studying the relationship between classical and quantumphysics. Designing such algorithms is complicated by the rather nonintuitive character of quantumphysics. Recently, reversible computational models have been studied mainly in the context of quantum computation, as (without measurements) quantumphysics is inherently reversible. In other words, what is there that is so good in logic that quantumphysics should obey it? Such an approach has particular value when considering the particular kind of developments in quantumphysics and its applications that we are experiencing today. The state vectors of entangled particles still evolve in this space-time in accordance with the laws of quantumphysics; that is, they undergo unitary evolution. The indeterminism which belongs to quantumphysics is a subjective indeterminism. The prominent orthodox argument, that quantumphysics gives up causality in principle while classical physics gave it up only in practice, itself crystallized in this tendentious construction of the past. We will see that dynamical systems and quantumphysics independently suggest very important, but different, notions of randomness, giving rise to a different role for probabilities in their various contexts. Such are the oddities of quantumphysics. According to the correspondence principle, classical physics is a limiting case of quantumphysics - as we approach higher quantum numbers, quantum results merge into classical ones.
