A fluorescent protein based on one made by the bioluminescent crystal jelly can be used as a quantum sensor

Quantum sensors made from a glowing protein can be produced by living cells and could be used to much more accurately measure tiny changes in the body. This could one day help with early disease detection or tracking how cells form.
Sensors based on the quantum mechanical property of spin can measure temperature, magnetic fields and other phenomena much more sensitively than conventional devices. They have already been shown to work in living animals, such as detecting the magnetic…
