Scientists mathematically proved unattainable absolute zero of temperature Source:

The Laws of thermodynamics, which are the cornerstones of modern physics help us explain the behavior and change of the physical properties of objects and environments under certain conditions and circumstances. The first two laws in the fundamental plan never was exposed to criticism and revision, what can be said about the third. He was bred by the German physicist and chemist Walter Nernst in 1906-1912 years, however, scientists are still arguing about its viability.

From this it follows that:

"the ideal Entropy of any pure substance in thermodynamic equilibrium approaches zero when approaching the absolute zero of temperature, as well as the temperature of any pure substance in thermodynamic equilibrium approaches zero when the entropy of the substance approaches zero"".

In a recent study, the results of which , researchers from the University College of London proved that in a system where entropy can not reach absolute zero, to reach (a certain number of steps) of a body temperature equal to absolute zero, impossible.

"We proved that in the presence of a limited number of steps to cool a system to absolute zero is not possible. Then we came to the conclusion that it is impossible to cool a system to absolute zero for a certain period of time and established a relationship between time and maximum low temperature, which is cooling rate", — said Luis Masanes, one of the authors of the new study.

The Researchers hope that these findings, other scientists will begin to take more seriously the third law of thermodynamics, which, speaking in plain words, speaks of unattainability of absolute zero temperature. In addition, the researchers believe that their work could have important practical value. As the understanding of the cooling process and its maximum value will help us, for example, further development of technologies of quantum computing.

In recent years the field of quantum computing attracted attention from the most famous tech giants, such as IBM, which is already actively trying to bring quantum computing into commercial production.

The Understanding of the third law of thermodynamics and the levels at which cooling is performed, will make progress in quantum research even further, as one of the key problems of these calculations is the overheating of quantum systems.
