Physicists ease path to entanglement for quantum sensing

A quantum mechanical trick called 'spin squeezing' is widely recognized to hold promise for supercharging the capabilities of the world's most precise quantum sensors, but it's been notoriously difficult to achieve. In new research, physicists describe how they've put spin squeezing within better reach.
