Repurposing Biology for Quantum Sensing
Quantum states are remarkably sensitive to environmental changes, making them ideal for precision sensing. However, their fragility poses challenges, especially within the complex and unpredictable environment of living cells. Previous attempts to introduce synthetic quantum sensors into biology have struggled with issues like targeting, efficiency, and durability.
Now, scientists at the University of Chicago have achieved a major milestone by repurposing fluorescent proteins, commonly used in biological imaging, as quantum sensors. Since these proteins can be encoded in DNA, cells can be engineered to produce them, ensuring precise targeting at the sub-cellular level. This innovation marks the emergence of quantum devices built from biological materials.
The Science Behind Biological Qubits
The breakthrough centers on a quantum state known as the triplet state found in certain fluorescent proteins. While these states were known, their use as quantum sensors is novel. Researchers discovered that the triplet state could act as a qubit, storing quantum information and allowing optical readouts with specialized microscopes.
- Measurements of magnetic and electric fields deep within cells are now possible.
- By integrating qubit functionality into proteins, scientists can design quantum materials harnessing nature’s own principles of evolution and self-assembly.
Experimental Achievements and Implications
The research team focused on a yellow fluorescent protein, first confirming its quantum state could be read at extremely low temperatures. They then showed similar results in mammalian cells, and even expressed the protein in bacteria, successfully detecting magnetic fields inside living systems.
These advances pave the way for revolutionary applications, such as magnetic resonance imaging (MRI) at the level of individual cells. Such capability could provide atomic-scale insights into cellular machinery and reveal how drugs interact with proteins far beyond the reach of today’s fluorescence microscopy.
Facing Challenges, Forging Ahead
While these results are promising, biological qubits must become even more stable and sensitive to thrive in the chaotic environment of living cells. Developing new quantum sensing techniques will be essential to fully realize their potential.
Nevertheless, this foundational achievement is transformative. By leveraging biology itself as the quantum platform, scientists are opening a new window into the quantum properties of life.
Towards Quantum-Powered Biology
This breakthrough exemplifies the synergy between quantum technology and the life sciences. By engineering biological qubits, researchers can soon unlock detailed views of the cell’s inner workings and molecular machinery. Though refinement is needed, these groundbreaking steps hint at a future where quantum sensors revolutionize both biology and medicine.
