WebbQuantum mechanics, perhaps one of the most successful scientific theories in the history of mankind, is in some respects counterintuitive, challenges our imagination, seems to violate fundamental principles of classical physics, and raises many questions that have preoccupied the minds of physicists and philosophers since the early 1930s. WebbIn quantum physics, a quantum fluctuation (also known as a vacuum state fluctuation or vacuum fluctuation) is the temporary random change in the amount of energy in a point in space, [2] as prescribed by Werner Heisenberg 's uncertainty principle. They are minute random fluctuations in the values of the fields which represent elementary ...
