This kind of article is typical of a half-understanding, holding chicken feathers as arrows. It's very good that people are interested in quantum computing, a cutting-edge technology, but you should look at serious sources.

Recently, a friend came to me and said that he saw an article titled "China's Quantum Technology Will Be Surpassed?" American scientists break through the bottleneck, or really master the quantum computer (https://www.sohu.com/a/518705597_121290916), ask whether this is reliable? As soon as I looked, this article was talking about a technical route that I already knew, topological quantum computing. Take a look at the description of this article:
"Recently, Researchers in the United States have discovered a completely new state of matter called 'topological superconductivity'. It is said that this new state of matter can greatly improve the performance of quantum computers, which is of great significance.
……
Javad Shabani, an assistant professor of physics at New York University, said: "Our study has successfully revealed the experimental basis for a new state of topological superconductivity that will greatly increase the speed of quantum computing and improve the way quantum storage is done." I believe that this concept can be expanded and eventually used to build qubits to achieve quantum computing and storage in the true sense, which is of great significance! ’”
The description of the technical principles in this article is confusing and confusing, so I will not quote it. The biggest problem is the title party, the so-called "Chinese quantum technology will be surpassed" is purely the author's brain supplement. So I replied to this friend:
Quantum computing has a variety of possible physical systems, that is, several technical routes, the hottest is superconductivity and optics, in addition to ion traps, cold atoms, etc., everyone is trying to develop. Topological quantum computing is not a new thing, but a long-proposed technical route, which is currently in a relatively backward state, and suffered a major setback last year: an experimental article that was previously considered very important in the industry was found to be unable to repeat and was retracted. This kind of article is typical of a half-understanding, holding chicken feathers as arrows. People are very interested in quantum computing, which is a cutting-edge technology, but you should look at serious sources, such as the official media and my popular science book "Quantum Information Shorthand". If you look at the marketing number, you will be taken to the ditch by them.
