LapPt3P Rare Topological Superconductor Quantum Computing
University of Kent and the STFC Rutherford Appleton Laboratory researchers have discovered a new rare topological superconductor, LaPt3P, which could be used in the future of quantum computing. This discovery was made through muon spin relaxation experiments, and solves the issue of elementary units of quantum computers (qubits) losing their quantum properties from electromagnetic fields. Topological superconductors host protected metallic states on their surfaces. Read more for two videos on quantum computing and additional information.



To verify that LaPt3P’s properties are sample and instrument independent, two different sets of samples were prepared in the University of Warwick a well as in ETH Zurich. Muon experiments then took place at two different types of muon facilities: in the ISIS Pulsed Neutron & Muon Source in the STFC Rutherford Appleton Laboratory and Switzerland’s Paul Scherrer Institute (PSI).
