Polzik of the Niels Bohr Institute in Copenhagen, and their colleagues teleported traits of a dim laser pulse, including the strength of its electromagnetic field, onto a cloud of 1 trillion cesium atoms. Another example is instead of having a physical sensor on electromagnetic valve actuators, signals from the electromagnetic field generated could be used by software to "sense" the position of the valve without a physical sensor.
