Quantum Computers to get their Scale Boosted up Through New Super-Cooled Microwave
According to the latest reports, a research team from Finland has shared a promising piece of information with the technological world in terms of Quantum Computing. The researchers have revealed that they have successfully developed a circuit that will generate microwave signals that will be of very high quality.
The particular microwave signals generated by the newly developed circuit are the ones that are needed for controlling quantum computers. The particular circuit would prove to be extremely useful for quantum computers that tend to operate in close to absolute zero temperatures.
With the latest development, a new milestone has been achieved in the quantum computing sector. This is the first step that quantum computing has taken, getting closer to quantum processor technology for the controlling of quantum computers.
The research team from Finland was really glad in making the announcement and sharing useful information surrounding their development. According to them, the latest development is going to help them develop processors with more quantities of qubits.
For a long period of time, it was the mechanism that went behind limiting the quantum computers’ size. The particular mechanism was responsible for the controlling of quantum processors’ qubits.
In order to control the qubits, the microwave pulses are used in series. These microwave pulses are brought to quantum computers through broadband cables. This is because the quantum computers and their processors operate in an environment that is present near absolute zero temperatures.
However, the number of broadband cables could only bring a certain amount of microwave pulses. Therefore, as the number of qubits increased within the processors, it would require more cables to bring more microwave pulses from room temperature to absolute zero temperature.
This is the reason why the size of the quantum processors was getting limited because the number of cables would also increase with the number of qubits. In addition to the processors, even the size of the refrigerators would have been increased that are required to cool the qubits. Once the size of the refrigerator was increased, only then the number of cables to be cooled by the refrigerator could be increased.
It has been revealed that the team of researchers from Finland are actually from the VTT Technical Research Centre and Aalto University.
According to the research team, the microwave source they have developed would be doing the same job as quantum processors operating at low temperatures. The team has revealed that the particular source would actually be an on-chip device.
Once launched and operated, the quantum processors can have them integrated inside of them. With the new device, there will be no need for the cable that is responsible for generating different temperatures.
