A group at the MIT led by Prof. Vladan Vuletić has recently generated significant amount of spin squeezing-a type of quantum entanglement-in an ultracold vapor of ytterbium-171. Spin squeezed states (SSS) can be used to overcome the standard quantum limit (SQL) which bounds state-of-the-art atomic sensors like optical clocks. The latter deploy a dilute vapor...
