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 ...

The xCORE XS1-L4-64 integrates four 32-bit logical processor cores at a price that is comparable with competing single-core devices. The xCORE XS1-L4-64 integrates four 32-bit logical processor cores ...
