New pre-print describes codes that “move” logical ancilla qubits up and down to significantly reduce the error rate ...

French startup Alice and Bob announced today a new way to reduce errors in ...

To shrink error rates in quantum computers, sometimes more is better. More qubits, that is. The quantum bits, or qubits, that make up a quantum computer are prone to ...

Shares of Rigetti Computing were higher Wednesday after the company said it had achieved its mid-year milestone of reducing the error rate for one of its quantum ...

In September, Microsoft made an unusual combination of announcements. It demonstrated progress with quantum error correction, something that will be needed for the ...

The company said it is able to reduce error rates in its quantum computing capabilities by 1,000-fold thanks to four-dimensional geometric codes. Quantum Computing ...

Scientists have designed a physical qubit that behaves as an error-correcting "logical qubit," and now they think they can scale it up to make a useful quantum computer using a few hundred. When you ...

There’s a strong consensus that tackling most useful problems with a quantum computer will require that the computer be capable of error correction. There is ...

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 ...
