In spectroscopy, this property causes a spectral line to acquire a Lorentzian profile and a so-called "natural" line width.
A state which minimizes this property can be constructed using an operator equal to the exponential of one-half times the quantity "Z A squared minus Z-star A-dagger squared," where Z is a complex number and A and A-dagger are the ladder operators. Those states which minimize this property are referred to as "squeezed." In spectroscopy, this property causes a spectral line to acquire a Lorentzian profile and a so-called "natural" line width. The (*) coherent states of the quantum harmonic oscillator minimize this property, which is also minimized by any Gaussian wavepacket. This property is quantified by a product which, for canonically conjugate observables, has a minimum value of h-bar over 2. For 10 points, name this property from quantum mechanics, which restricts the simultaneous measurement of position and momentum.
