Contribution

It reveals a genuine quantum stochastic resonance phenomenon driven by quantum shot noise in superradiant Raman scattering.

Findings

Maximum scattering occurs at a specific non-zero quantum noise level.

Atomic response peaks at the square root of the number of atoms.

Quantum shot noise enhances superradiant scattering under optimal conditions.

Abstract

We discuss the effects of noise on the timing and strength of superradiant Raman scattering from a small dense sample of atoms. We demonstrate a genuine quantum stochastic resonance effect, where the atomic response is largest for an appropriate quantum noise level. The peak scattering intensity per atom assumes its maximum for a specific non-zero value of quantum noise given by the square root of the number of atoms.
