"laser-continuously-cooled (10 millionths degree above absolute zero) strontium-88 atoms continuously loaded into/ react with light inside circular optical cavity, helping realize quantum sensing/ simulate complex quantum systems... atoms make laser cavity give off laser light for hours... lasing mechanism stabilizes cavity frequency... only occurs in continuous, as opposed to cyclic experiments... quantum computing, ultranarrow linewidth lasers"
