Its creators claim that the refrigerator can lead to the most reliable quantum computing.
Has reached a group of researchers Create a record cold refrigerator That may help computers Quantum To work better. The basic units of quantum computers must be maintained at temperatures close to complete zero to act without errors.
A New cooling technology Created by researchers at the University of Salmers Technology (Sweden) and the University of Maryland (USA) All skills of quantum computing.
The cooling methods used today are called diluted refrigerators, according to the University of Salmers Technical University, carrying quitts above the entire zero. In an experiment, a new quantum refrigerator came with quitts for 22 milligels, which is a factor 10,000 times colder than the ambient temperatureAccording to the Research Group.
Complete zero or zero Kelvin, which is equal to Less than 273,15 degrees CelsiusThe most trusted quantum computing can be, but it is very difficult to reach a complete zero Reduce the temperature.
The refrigerator is “completely autonomous”
“If you think about what is physically temperature, these are essential vibrations. And you may think that an object is very vibrating as a very vibrant to a level. Dynamics Quantum he is completely still still, This is the so -called complete zero“Euronevs Next, explains to Simon Casparnetti, a co -professor of Salmer’s Technology University and a prominent writer of the study.
The team got these vibrations 10,000 times smaller, which for them “History Minimum” To the molds of question. Unlike the diluted cooling methods that require constant external control, this quantum refrigerator operates once the refrigerator is loaded.
The refrigerator uses three Quitz It operates on a system based on a system, in which the hot and cold environments need to be refrigerated part of the quantum system to remove the heat of an objective QBIT that communicates in a certain way.
“The energy of the thermal environment was replaced by one of the two quits of the quantum refrigerator, Pumps Target Chbit to Heat from Second Quit From the cooler quantum refrigerator, “Nicole Gunker Hallburn, a professor of physics at the University of Maryland, is warmed in a cold environment in which the target heat is finally poured,”
Casparintey makes it clear ”The refrigerator is completely autonomousThis means, basically, you need to connect only with a warm and cold source to act. It contradicts other techniques, for example, pulses with accurate or other restrictions “, and” on the basis of “basis, it runs, the quits cool, turn off, and the calculation begins. “
Carry the thermal mechanics of theory into practice
Quantum thermal mechanics, which combines it Body Quantum and thermal dynamics, which is a field, according to researchers claiming that it is often theoretical until now. “Over the last 50 years, we have made many components miniature, especially electricity, but not all,” he explains, “We have really had the desire to create a quantum machine, which was useful for a thermal machine.”
Researchers say that This refrigerator helps to work with very little errors And a long time on quantum computers. Matrix Quantum managed to reduce the error rate of computer science 20 timesFrom 0.02 to 0.01. It may seem smaller, but researchers say that it is important to reduce errors to guarantee the reliability of quantum computing calculations.
Quantum computers won’t change classics
Quantum computers can Set up the revolution in technologies With applications in basic, medicine, energy, encryption, artificial intelligence and logistics in various fields of society. However, researchers say you need to continue to work, so quantum computers can solve problems.
“These machines have Improve many things before being effective. We also need to improve the way we use these resources. We still do not understand how to use quantum resources to make useful calculations and solve useful problems, ”says Kasparinetti.
He also says that there is the main intelligent of the study The wrong idea of changing quantum computers to the classicsLike our laptops. It is rather Technology to upgrade computers Classic computers are required to continue to run a quantum system, such as classic, logistics or innovation.
“Tests like we have done are that we can be very close to quantum components, I think this is a trend we see in the future,” says Kaspardy. Researchers expect that more quantum autonomous machines will be created. “The next question is that the other issues can be solved autonomously”Concludes the main researcher of the study.
