Researchers have long sought to detect quantum effects in macroscopic objects, analogous to the superposition of states in Schrodinger’s cat that is both dead and alive. The development of ultrasensitive measurement techniques used in quantum computing and gravity wave detection may offer a way to experimentally test these ideas. Vinante et al. have used amplifier feedback to cool oscillation modes in a one-metric-ton aluminum bar that forms the active element in the AURIGA gravity wave detector. The effective temperature was 0.2 mK . Although other experiments have achieved lower temperatures, the AURIGA resonator is orders of magnitude more massive. Such feedback techniques may enable researchers to approach a regime where quantum effects become apparent.
