（谐振子的）相干态是由欧文·薛定谔（Erwin Schrödinger，1887-1961）在量子力学之初引入的，以回应洛伦兹关于薛定谔的波函数不显示经典运动的抱怨。薛定谔获得了具有基态宽度的高斯解。这些高斯解的坐标和动量的期望值随时间振荡，就像经典谐振子理论中的坐标和动量一样。
Coherent states (of the harmonic oscillator) were introduced by Erwin Schrödinger (1887–1961) at the very beginning of quantum mechanics in response to a complaint by Lorentz that Schrödinger's ► wave function did not display classical motion. Schrödinger obtained solutions that were Gaussians having the width of the ground state. The expectation values of the coordinate and momentum for these Gaussian solutions oscillate in time in just the same way as the coordinate and momentum in the classical theory of the harmonic oscillator.
