From glow to qubits: fluorescent proteins become inside-cell quantum sensors

Researchers are turning fluorescent proteins into qubits to enable quantum sensing inside living cells, offering the potential for ultra-sensitive imaging of magnetic fields, neural activity and cellular stress. While proof-of-principle work exists and proteins are easier to place precisely in cells than NV-diamond sensors, challenges remain in protein stability and boosting sensitivity for robust biomedical applications.

Magnetic Switch Lets Protein Fluorescence Be Remotely Tuned in Cells

Researchers have engineered magnetically responsive fluorescent proteins (MagLOV) that can be dimmed or brightened in cells and living tissue using magnetic fields and radio waves, enabling remote control of protein function for potential biosensors or therapies. Demonstrated in bacteria and with methods to map MagLOV-expressing cells in solid blocks, the work relies on a quantum magnetic resonance effect in electron pairs and could extend to animal studies as magnetically targeted tools are developed.

Scientists Develop Fluorescent Protein-Based Biological Qubits

Researchers have developed a genetically encodable fluorescent protein, EYFP, as a spin qubit for quantum sensing, demonstrating optical initialization, control, and readout of its spin states at cryogenic and room temperatures, with potential applications in biological sensing and imaging.
