Room-Temperature High-Purity Quantum State Achieved: A Breakthrough in Quantum Sensing

Researchers at ETH Zurich have achieved a breakthrough in quantum sensing by levitating three nanometer glass spheres using optical tweezers at room temperature. Remarkably, 92% of the spheres' motion was attributed to quantum effects, eliminating the need for extremely low temperatures typically required for observing quantum phenomena. This high-purity quantum state opens doors for developing quantum sensors for applications such as medical imaging and highly precise navigation systems.
