Majorana 1, a quantum chip that relies on topological qubitsJohn Brecher/MicrosoftMicrosoft researchers say they have created topological qubits, long sought-after components for a radically different kind of quantum computer. This isnt the first time the firm has made this claim it attempted to produce these error-proof quantum bits in a similar experiment in 2023, but the results werent fully conclusive, raising doubts among colleagues in the field about whether it has fully worked this time.Topological qubits could solve one of quantum computings biggest problems: all
