Computers also make mistakes. These are usually suppressed by technical measures or detected and corrected during the calculation. In quantum computers, this involves some effort, as no copy can be ...

Carbon code is different, says Svore. “We do not consider the Carbon code to be an LDPC code,” she says. Technically, Carbon code is a stabilizer code of the Calderbank-Shor-Steane variety, which is a ...

Quantum computing is still in its infancy, easily beaten by traditional computers. One of the biggest challenges? The fact that quantum bits — qubits — are much more fragile than the bits in silicon ...

The company says it has cracked the code for error correction and is building a modular machine in New York state. IBM announced detailed plans today to build an ...

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 ...

Subspace codes are a class of error-correcting codes defined over the set of subspaces of a finite vector space. They have emerged as a powerful tool in network coding, where information is ...

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 ...

Following up on Microsoft’s announcement of a qubit based on completely new physics, Amazon is publishing a paper describing a very different take on quantum computing hardware. The system mixes two ...
