Quantum fluctuation — In quantum physics, a quantum fluctuation is the temporary change in the amount of energy in a point in space, arising from Werner Heisenberg s uncertainty principle.According to one formulation of the principle, energy and time can be related by … Wikipedia
Quantum annealing — In mathematics and applications, quantum annealing (QA) is a general method for finding the global minimum of a given objective function over a given set of candidate solutions (the search space ), by a process analogous to quantum fluctuations.… … Wikipedia
