Researchers have demonstrated the first complete set of logical quantum operations on a silicon-based processor, encoding ...

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 ...

Researchers at the University of Innsbruck, together with partners from Sydney and Waterloo, have presented a new diagnostic method for quantum computers. It makes errors in individual quantum bits ...

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 ...
