Stable qubit is a prime candidate for universal quantum computer

Researchers from QuTech improved the so-called "Andreev spin qubit" in a critical way and believe it can become a prime candidate in the pursuit of a perfect qubit. The new type of qubit is created in a more reliable and intrinsically stable way, compared to previous versions, by combining the advantages of two other types of qubits. The team has published their work in Nature Physics.
