Scientists have discovered the cause of a persistent glitch that continues to disrupt superconducting quantum computers, even ...

By reducing the ratio, quantum computers would need a thousand times fewer qubits, making them significantly easier to build and scale, while also requiring less power and computational ...

Researchers at Google Quantum AI and collaborators have developed a quantum processor with error rates that get progressively smaller as the number of quantum bits ...

Surface code: illustration of how error correction works for bit and phase flips. The measure qubits on light blue backgrounds check for phase flip errors while the ...

For the first time, a quantum computer has improved its results by repeatedly fixing its own mistakes midcalculation with a technique called quantum error correction ...
