A team has realized a key milestone in the quest for stable, scalable quantum computing. For the first time, the team has created a programmable, logical quantum processor, capable of encoding up to ...

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 ...

Quantum computers are alternative computing devices that process information, leveraging quantum mechanical effects, such as ...

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

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 ...
