A few days ago, Google claimed ‘quantum supremacy’. Google used to work on ordinary computers for 1000 years, claiming that their quantum computer did that job in 20 seconds. Meanwhile, Microsoft is also researching such computers. But they are trying to change the way Cubit works.
The company claims that if successful, not only theoretical, it can be used to solve real problems.
At the core of Microsoft’s research is the topological cubit. They have been researching this for five years. Now it’s ready for use, said Christa Saver, general manager of Microsoft’s quantum computing division, at the IEEE International Conference on Rebooting Computing Conference last Thursday.
The workings of quantum computers are complex. Creating is as difficult as creating a program is not easy. Works in a cooler environment than space. However, on a quantum computer, such work can be done on a normal computer, which is not possible. Christa cited examples of finding the most efficient way to make chemical fertilizers or finding the fastest route during traffic.
Normal computer stores information through 5 or 8. That means in a binary way. In the case of cubits, two bits can be stored together. It adheres to the principle of quantum physics called ‘superposition’. In addition, cubits interact with each other. This method is called ‘entanglement’. By combining these two methods, a quantum computer can examine many possible solutions to a problem. One problem, however, is that the cubit easily becomes ‘disturbed’. That’s why the core of a quantum computer is to be kept in a cool container.
Although individually, it is not possible to achieve quantum supremacy, many tasks can be done quickly within a fraction of a second via a qubit. He designed the quantum computer to make a single logical cubit by adding multiple cubits at a time to correct the error of the cubit. The point is, even if some companion cubit doesn’t work, overall logical cubit can provide fast computing services.
The advantage of Microsoft’s topological cubit is that the number of companion cubits is less than that required to create a logical cubit, said Christa Savor. In general, creating a logical cubit usually requires between 3 and 25,000 companion cubits. And for Microsoft, it takes 3 to 5 companion cubits. That is, Microsoft can create quantum computers using fewer cubits. In addition, the company has shown progress in working with advanced control systems and software for quantum computers. The only problem is – Microsoft has not yet released the topological cubit.
