Observation of high-intensity sub-Poissonian light using an optical parametric oscillator.
TLDR
In this paper, the authors reported the observation of high-intensity sub-Poissonian light using the correlated ''twin'' beams generated by an optical parametric oscillator, where the intensity fluctuations in one of these beams are reduced by a feed forward correction mechanism that monitors the intensity of the second beam.Abstract:
We report the observation of high-intensity sub-Poissonian light using the correlated ``twin'' beams generated by an optical parametric oscillator. The intensity fluctuations in one of these beams are reduced by a feedforward correction mechanism that monitors the intensity of the second beam. The observed reduction in noise power is up to 24% below the shot-noise limit.read more

Quantum Measurement and Control
TL;DR: In this paper, the authors present a comprehensive treatment of modern quantum measurement and measurement-based quantum control, which are vital elements for realizing quantum technology, including quantum information, quantum metrology, quantum control and related fields.

Experimental realization of sub-shot-noise quantum imaging
TL;DR: In this paper, a sub-shot-noise imaging using spatial quantum correlations between parametric down-conversion light beams is demonstrated, which exhibits a larger signal-tonoise ratio than is possible through classical imaging methods.

Sub-Poissonian processes in quantum optics
TL;DR: In this article, a review of methods for generating sub-Poissonian light and related concepts is presented. But the authors focus on the conceptual foundations and developments in laser theory that lead to the possibility, already demonstrated experimentally, of linewidth narrowing and sub-poissonic light generation in lasers and masers.
