Exploring fault-tolerant qubit computing is an important way to finally achieve large-scale quantum computing. The Majorana zero-energy module is considered to be the basis for implementing topological qubits because it is protected by topological degeneracy, satisfies non-Abelian statistics, and has characteristics of resistance to local interference and high fault tolerance. However, detection of such heterostructures in the Majorana zero-energy mode requires a complex manufacturing process, and observation requires extremely low temperatures and an applied magnetic field. These conditions have brought great difficulties to the possible application of the Majorana zero-energy mode. And challenges. With the support of quantum control and quantum information key projects, Professor Wang Jian's team and collaborators of the Quantum Materials Science Center of the School of Physics of Peking University successfully prepared large-scale, high-quality single layers on the strontium titanate substrate by molecular beam epitaxy In the FeTe0.5Se0.5 high-temperature superconducting thin film, a one-dimensional atomic chain defect formed by the uppermost Te / Se atom deletion was found on the film surface, and zero energy binding was observed at both ends of this one-dimensional atomic chain defect State, the spectral properties of this zero-energy bound state are consistent with the interpretation of Majorana ’s zero-energy mode. This work reveals for the first time the zero-energy excitation at the end of a type of topological line defect in a two-dimensional high-temperature superconductor FeTe0.5Se0.5 single-layer thin film. It has the advantages of a single material, higher operating temperature and zero applied magnetic field. The applicable topological qubits provide a possible solution.
