Theoretically, the technology allows to reduce the temperature that it will reach absolute zero.

Scientists of the U.S. National Institute of standards and technology cooled the membrane to one-fifth of the quantum of the minimum that was previously thought impossible, according to Science Alert.

The membrane made of aluminium with a size of 20 micrometers in diameter and 100 nanometers thick cooled to a temperature of 360 microkelvins. Thus, the researchers achieved the lowest temperature obtained in labs using lasers.

“This is much colder than any natural object in any point of the Universe,” said one of the researchers, John Teufel.

Under normal cooling to very low temperatures there is a limit of quantum back action. So call the situation when the dimension of the achieved ultra-low temperature heats the cooled object. Therefore, physicists have not measured the temperature of the membrane, and the level of fluctuations side mounts .

Theoretically, the technology allows to reduce the temperature that it will reach absolute zero. Based on the new technology of refrigeration to create a more sensitive optical and mechanical sensors, as well as more reliable quantum computers.

“Sensors will become more sensitive. You will be able to store information longer. If you use this approach in a quantum computer, you can get the result without distortion,” added John Teufel.

Earlier it was reported that scientists have found a way to treat teeth without fillings.
