Scientists have created a quantum microscope that helps to see previously invisible cellular structures

An international scientific group of engineers from Australia and Germany has created a new quantum a microscope that was able to discern cellular structures that were previously just invisible.

So, according to the engineers, their development will create completely new biotechnologies, as well as transform existing technologies (from navigation to medical imaging).

The Limit of Modern Microscopes and Overcoming It

As you know, the maximum possible performance of light microscopes rests on the so-called level of random noise generated by elementary light particles. In this case, it is the discreteness of photons that is responsible for such parameters as maximum sensitivity, resolution and speed.

In order to optimize these parameters, engineers usually follow the path of increasing the intensity of the light beam and even replacing it with laser sources.

But as practice has shown, laser microscopes cannot always be used for a detailed study of biological systems. Since bright lasers quickly destroy the cells under study.

Engineers at the University of Queensland put forward their idea that biological imaging can be enhanced without increasing light intensity through the use of quantum photon correlations.

Further experimental work with engineers from the University of Rostock showed that, thanks to the use of quantum correlations, it is possible to increase the "resolution" of the microscope by almost 35%, in comparison with conventional microscopy, which does not damage living cage.

Scientists have managed to create a coherent Raman microscope with subwavelength resolution, as well as bright quantum-correlated illumination, which made it possible to examine in detail the molecular bonds directly in cage.

As Professor W. Bowen, the microscope they created is based on the so-called quantum entanglement, which A. Einstein called "eerie interactions at a distance."

And at the moment it is the first microscope in the world, implemented on the basis of entanglement with characteristics that significantly exceed the best analogs on the "classical" solutions.

Scientists are confident that their breakthrough will give an impetus to the development of completely new technologies in the most different areas, ranging from new navigation devices, ending with more advanced devices MRI.

The engineers also consider it a huge success that their microscope finally overcame the so-called The "hard limit" of conventional microscopes, and now scientists can literally look inside living cells.

Well, we will observe how technologies will develop in this direction and what else can scientists develop using quantum entanglement.
