Arbitrary logical state preparation protocol. Top panel: The surface code is divided into 5 regions, the central data qubit, regions I, II, III, and IV. The logical operators Z ̂_L and X ̂_L intersect ...

In quantum computing, a quantum bit or “qubit” is one unit of information, just like a binary bit in classical computing. For more than two decades, physicists and engineers have shown the world that ...

There’s widespread agreement that most useful quantum computing will have to wait for the development of error-corrected qubits. Error correction involves ...

Microsoft Thursday said the next upgrade of its Windows Server operating system will scale up to 256 logical processors. Microsoft defines a logical processor as the number of physical processors ...
