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 ...

Researchers at Harvard University claim to have created a programmable, logical quantum processor, that can encode up to 48 logical qubits, and execute hundreds of ‘logical’ gate operations. Their ...

According to Cointelegraph, a team of researchers funded by the United States Defense Advanced Research Projects Agency (DARPA) and led by scientists at Harvard with support from QuEra Computing, the ...

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 ...

A logical, or Boolean, expression returns a value that is evaluated as true or false. In the macro language, any numeric value other than 0 is true and a value of 0 is false. When the macro processor ...
