Snaphots freezing a nanoswing: Accurate position measurement overcomes thermal fluctuations

Physicists at AMOLF have managed to cool a swinging, nanosized string to near-zero temperature without using external refrigeration. In their experiment, the cooling is an intrinsic result of a 'snapshot' position measurement they conducted on a specially designed nanostructure. The snapshot method, developed in AMOLF's Photonic Forces group, offers opportunities for new applications in quantum sensing with unprecedented sensitivity. The researchers describe their findings in an article published on September 9th in Physical Review Letters.
