"Our quantum error-correcting code has a greater than 1/2 code rate, targeting hundreds of thousands of logical qubits," explains Kasai. "Moreover, its decoding complexity is proportional to the ...

If you’ve ever sent a text message, played a CD, or stored a file in the cloud, you’ve benefited from error correction. This revolutionary idea dates back to the ...

Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

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 ...

On Tuesday, Microsoft made a series of announcements related to its Azure Quantum Cloud service. Among them was a demonstration of logical operations using the largest number of error-corrected qubits ...

More from less Concepts from gauge theory could be used to reduce the number of qubits needed to do quantum error correction. (Courtesy: iStock/Quardia) Concepts from ...

How do you construct a perfect machine out of imperfect parts? That’s the central challenge for researchers building quantum computers. The trouble is that their elementary building blocks, called ...
