WebThe Fourier Transform of a Gaussian wave packet is also a Gaussian. We will show later that a Gaussian is the best one can do to localize a particle in position and momentum at the same time. ... We achieved this by making wave packets which are superpositions of states with definite momentum. The wave packets, while localized, have some width ...
