Summary

Story summary

University of Chicago researchers developed a jellyfish fluorescent protein qubit for sensing.
It detects magnetic and electrical signals without retrofitting quantum devices.
A confocal microscope manipulated the spin of enhanced yellow fluorescent protein (EYFP) as a qubit in biological samples.
The EYFP qubit operates for about 16 microseconds and decays.
Challenges include cooling needs and sensitivity gaps versus solid-state sensors.
