When atoms are cooled to just above absolute zero degrees Kelvin (-460 xF), a state of frictionless matter known as Bose-Einstein Condensate (BEC) is created that can be used to dramatically increase the performance of devices such as gyroscopes, accelerometers, gravimeters and magnetometers," said ColdQuanta President Rainer Kunz.
