- This is a non-specialist introduction, drafted by Jac:
- Plamen Petrov's research involves the manipulation of light in such a manner that it is put into a Squeezed State. This state can be obtained if the light's electric field strength ε for some phases θ has a quantum uncertainty smaller than that of a coherent state. A coherent state is a specific quantum state of the quantum harmonic oscillator. The terms squeezing thus refers to a reduced quantum uncertainty, i.e. the squeezed state must also have phases at which the electric field uncertainty is larger than that of a coherent state. In other words, the light is anti-squeezed.
