Photon [[Harmonic Oscillator State Vector]]s are a form of [[sub-Poissonian light]], which consists of photons, each emitted at a fixed time, $\Delta t$.  They are also a type of [[squeezed states]]. # photon statistics # quantum mechanical model These photons are modeled quantum mechanically as [bosonic](Boson) [[fock state]]s, $|n\rangle$ and these states are evidently [eigenstates](State%20vector#Decomposing%20state%20vectors%20into%20sets%20of%20orthonormal%20eigenstates) of the [ladder operator formulation](quantum%20harmonic%20oscillator%20Hamiltonian.md#ladder%20operator%20formulation) of the [harmonic oscillator hamiltonian](quantum%20harmonic%20oscillator%20Hamiltonian.md). ## creation and annihilation operators [[creation and annihilation operators]]s are equivalent to the [ladder operators](Harmonic%20Oscillator%20Ladder%20Operators.md) for the [quantum harmonic oscillator](quantum%20harmonic%20oscillator%20Hamiltonian.md#ladder%20operator%20formulation). #QuantumMechanics/QuantumOptics
