Researchers at Microsoft say they have created elusive quasiparticles called Majorana zero modes – but scientists outside the company are sceptical Microsoft researchers have made a controversial claim that they have seen evidence of an elusive particle that could solve some of the biggest headaches in quantum computing, but some experts are questioning the discovery. Quantum computers process information using quantum bits, or qubits, but current iterations can be prone to error. “What the field needs is a new kind of qubit,” says Chetan Nayak at Microsoft Quantum. He and his colleagues say they have taken a significant step...
