Proven unattainable absolute zero

Доказана недостижимость абсолютного нуляThe authors believe that their work will be useful in creating quantum computers.

Physics from University College London (UK) mathematically proved the impossibility of reaching absolute zero — the minimum allowable temperature of zero Kelvin (minus 273,15 degrees Celsius). A study published in the journal Nature Communications.

Scientists have wondered about how many steps will it take to cool a system to absolute zero. The answer depends on what work you need to do in order to transfer heat from the system outside.

Applying methods of the theory of quantum information, physicists have proven that no real system will never reach zero Kelvin, since that would require infinite number of steps.

The authors believe that their work will be useful in creating quantum computers, requiring the use of matter with the lowest possible temperatures. The physical impossibility of achieving absolute zero is postulated the third law of thermodynamics.
