Room-temperature quantum breakthrough freezes motion without cooling

ETH Zurich scientists have levitated a tower of three nano glass spheres using optical tweezers, suppressing almost all classical motion to observe quantum zero-point fluctuations with unprecedented precision. Achieving 92% quantum purity at room temperature, a feat usually requiring near absolute zero, they have opened the door to advanced quantum sensors without costly cooling.
