The Financial Times reports that Microsft and Google are about to announce two major breakthroughs in their respective research on quantum computing. While IBM has already confirmed the creation of a quantum system of 50 cubits, Microsoft can give the bell with the creation of a revolutionary cubic, according to the British newspaper.
Todd Holmdahl, who directs Microsoft’s quantum research, explains that his group is about to solve one of the biggest problems with this technology: the intrinsic fragility of the cube, which causes numerous reading errors that interfere with the system.
A cubic or quantum bitIt is a quantum system with two own states that can be manipulated arbitrarily. It is also understood by cúbit the information that contains that quantum system of two possible states. In this sense, the cube is the minimum unit and therefore constitutive of the theory of quantum information.
Microsoft would have developed a type of cube that separates electrons and thus manages to store information in different places at the same time. Even in case of quantum decoherence, the information stored in the cube is never lost.
The quantum decoherenceis the term accepted and used in quantum mechanics to explain how a physical system, under certain specific conditions, stops exhibiting quantum effects and goes on to exhibit a typically classical behavior, without the unusual effects typical of quantum mechanics.
Holmdahl emphasizes the importance of this finding by pointing out that if other quantum computers need 1,000 or 10,000 cubits, a quantum will suffice for Microsoft’s quantum computer, since its correction of errors is much greater.
Quantum computers require extensive error correction to compensate for the fact that the cubits are intrinsically fragile due to quantum decoathing. They only remain in a quantum state for a very short time and are difficult to read without interfering with the results.
The British newspaper highlights, however, that Microsoft has spent 12 years in quantum research and that until now it has not achieved any operating cost. But if it has really achieved that wonderful cúbit, we would be on the verge of an important technological revolution.
Although it is said that this announcement is imminent, we must bear in mind that having to go through the filter of peer-reviewed scientific journals before, that imminence is relative, although Holmdahl points out that in his day the Microsoft cúbit will be a moment important for science.
