Scientists managed to demonstrate entanglement in a biological system

Scientists from Northwestern University (Illinois, USA) have created quantum entanglement in the biological system. The achievement will clarify the fundamental conception of biology and can help create biological tools that operate according to quantum mechanics law.

Quantum entanglement is a phenomenon where two particles are able to keep in touch with each other, even being at different places of universe. In theory, we can send secure messages and ultimately create a super-high-speed "quantum Internet".

Experts from Northwestern University wondered whether it was possible to create a quantum machine on a biological substrate. Scientists have used green fluorescent proteins, which are responsible for bioluminescence. Using spontaneous four-wave mixing, they tried to entangle photons reproduced by fluorescent molecules of lipocalins.

Scientists achieved polarization of photons, where oscillations of light waves were in one direction. The proteins around the fluorescent molecules have protected the entanglement from destruction.

After witnessing possibility of this phenomenon in a biological environment, scientists intend to invent a biological substrate for a quantum machine and compare its work with a synthetic substrate.
