Therefore, according to the engineers, their development will create brand-new biotechnology and change existing technologies (from navigation to medical imaging).

As we all know, the performance of optical microscope is probably related to the random noise level generated by elementary light particles. In this case, the dispersion of photons determines the maximum sensitivity, resolution and speed.
In order to optimize these parameters, engineers usually increase the beam intensity or even replace it with a laser source.
But practice shows that laser microscope is not always used in the detailed study of biological systems. Because bright laser will quickly destroy the cells being studied.
Engineers from the University of Queensland put forward their idea that biological imaging can be enhanced without increasing light intensity by using quantum photon correlation.
Further experiments by engineers from the University of Rostock show that due to the use of quantum correlation, the "resolution" of the microscope can be improved by nearly 35% compared with the traditional microscope that destroys cells.
Scientists have successfully produced a coherent Raman microscope with sub-wavelength resolution and bright quantum correlation illumination, which makes it possible to directly examine molecular bonds in cells in detail.
According to Professor W. Bowen, the microscope they created is based on the so-called quantum entanglement, which A. Einstein called "long-distance creepy interaction".
At present, it is the first microscope based on entanglement characteristics in the world, and its characteristics obviously exceed the best simulation of "classic" solutions.
Scientists believe that their breakthrough will promote the development of new technologies in various fields, from new navigation equipment to more advanced nuclear magnetic resonance instruments.
In addition, engineers believe that their microscope finally overcame the so-called "hard limit" of traditional microscope, which is a great success. Now scientists can observe the internal structure of living cells in more detail.
Well, we will look forward to the technological development in this direction and what scientists can develop by using quantum entanglement.
