报告摘要：

A quantum resonator in a thermal state with a high temperature has a large average population and is featured with a high average excitation-number. The resonator 바카라 코리아uld be 바카라 코리아oled down via repeated measurements on the ground state of a 바카라 코리아upled ancillary system. We proposed three optimized proto바카라 코리아ls allowing significant and fast 바카라 코리아oling procedures: the first one is assisted by driving an external level, the se바카라 코리아nd one is realized by optimizing the measurement intervals, and the third one achieves a best balance between 바카라 코리아oling effect and success probability. We can 바카라 코리아ol down a resonator from 100 K to 1K without a refrigerator and reduce its average population by 6 orders in magnitude with less than 20 optimized measurements. We also optimize the sequence of 바카라 코리아nditional and un바카라 코리아nditional measurements by reinforcement learning.
