Agarwal Quantum Optics Online

The impact of Agarwal quantum optics on modern physics research cannot be overstated. His contributions have:

Using entangled states derived from Agarwal’s master equations, researchers are building sensors that beat the standard quantum limit. For example, his work on "quantum enhanced interferometry" allows for phase measurements with precision scaling as 1/N (Heisenberg limit) rather than 1/√N. agarwal quantum optics

In the context of resonance fluorescence (light scattered by a two-level atom), Agarwal predicted specific correlations in the cascade emission of photons. This work laid the groundwork for the generation of single photons on demand, which are the lifeblood of quantum cryptography and linear optical quantum computing.
