Scientists have proven mathematically unattainable absolute zero temperature

The laws of thermodynamics, is a cornerstone of modern physics, help us to explain the behavior and changes in the physical properties of objects and environments, under certain conditions and circumstances. The first two terms in the fundamental law never really been subjected to criticism and revision, which is not the third. He was bred by the German physicist and chemist Walther Nernst in the 1906-1912 years, but scientists are still arguing about its solvency.

Scientists have proven mathematically unattainable absolute zero temperature

From this it follows that:

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

In a recent study, whose results were published in the journal Nature Communications, researchers from University College London have shown that in a system where the entropy can not reach absolute zero, to achieve (for a certain number of steps) body temperature, absolute zero is impossible .

"We have 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, and over time, and also established a link between the time and the lowest possible temperature, which is for the cooling rate ", - says Luis Masanes, one of the authors of the new study.

The researchers hope that through these conclusions other scientists will be more serious about the third law of thermodynamics, which, if we talk in simple words, just say unreachable absolute zero temperature. In addition, the researchers believe that their work may be of practical importance. After all, an understanding of the cooling process and maximum values ​​will help us, for example, in the further development of quantum computing technologies.

In recent years, the scope of quantum computing has attracted very high attention from the most famous technology giants, such as IBM, which is already being actively trying to bring quantum computing commercialized.

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