A University of California (UC) Riverside research team, led by physicist Peng Wei, has developed a two-dimensional interface superconductor by combining trigonal tellurium and gold. This new material has the potential to carry and process quantum information more reliably, making it a possible replacement for the materials used in current quantum computers, which are prone to errors.
The team added the non-magnetic trigonal tellurium with a thin film of gold that had a surface-state superconductor. From there, the researchers saw quantum states with well-defined spin polarization at the interface of the two materials, as reported by UC Riverside News. This meant that it could be used to create qubits, which are the fundamental units of quantum information.
