The next major breakthrough for electronic products should be quantum computers. There is no real quantum computer in the world. However, many laboratories around the world are pursuing this dream with great enthusiasm. Although companies like IBM have made some progress, there are many obstacles to the study of real quantum computers. According to foreign media reports, a research team at the Aalto University in Finland developed a nano-sized refrigerator designed to help cool some of the components of the quantum computer. This study is considered to be theoretically feasible and recorded in the recent "natural transmission ( Nature Communications) magazine.
Ordinary digital computers operate on a binary system of 0s and 1s, called "bits." But quantum computers are far more powerful. They can operate on qubits and can calculate values ​​between 0 and 1. This will greatly increase the system heat of the quantum computer, and system heating will greatly affect the speed of the computer. Aalto University’s research team now uses nano-scale cooling systems to help heat the quantum computer.

The core technology of this cooling system is to use the quantum tunneling effect of electrons between atoms and capture photons to achieve the purpose of cooling. According to researchers, in quantum computers, information must be accurately calculated before initialization. At this stage, computers will be more prone to heat. By this method, cooling can keep the quantum computer system running smoothly.
To test their equipment, the team did not use real qubits, but instead used similarly functioning superconducting resonators and got good results. Researchers plan to use actual quantum in the future to adjust the equipment so that the equipment can be turned on and off faster and can work at lower temperatures.
