What

Mathematically, a coherent state is defined to be the (unique) eigenstate of the annihilation operator â with corresponding eigenvalue α. Formally, this reads, Since â is not hermitian, α is, in general, a complex number. Writing α and θ are called the amplitude and phase of the state . The state is called a canonical coherent state in the literature, since there are m… WebThe mean photon number is larger than zero in this case; a squeezed vacuum is a “vacuum” only in the sense that the average amplitude (but not the average photon number) is zero.
