摘要

Monitoring a mechanical object's motion, even with the gentle touch of light, fundamentally alters its dynamics. The experimental manifestation of this basic principle of quantum mechanics, its link to the quantum nature of light and the extension of quantum measurement to the macroscopic realm have all received extensive attention over the past half-century1'2. The use of squeezed light, with quantum fluctuations below that of the vacuum field, was proposed nearly three decades ago3 as a means of reducing the optical read-out noise in precision force measurements. Conversely, it has also been proposed that a continuous measurement of a mirror's position with light may itself give rise to squeezed light4'5. Such squeezed-light generation has recently been demonstrated in a system of ultracold gas-phase atoms6 whose centre-of-mass motion is analogous to the motion of a mirror.
