کوانتوم اپتیک و کوانتوم اپتومکانیک

Back action refers (in the regime of quantum systems) to the effect of a detector on the measurement itself, as if the detector is not just making the measurement but also affecting the measured or observed system under a perturbing effect. Back action has important consequences on the measurement process, and is a significant factor in measurements near the quantum limit, such as measurements approaching the Standard Quantum Limit (SQL).
