Code-based cryptography is a promising branch of post-quantum cryptography that exploits the inherent complexity of decoding linear error-correcting codes. Traditional schemes, such as the McEliece ...

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 ...

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 ...

The number and volume of warnings about a post-quantum cryptography (PQC) world are rising, as governments, banks, and other entities prepare for a rash of compromised data and untrustworthy digital ...

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 ...

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 ...

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki Ph.D.) and the Nagoya Institute of Technology (NITech, President: OBATA Makoto), collaborated with ...

Forbes contributors publish independent expert analyses and insights. Paul-Smith Goodson is an analyst covering quantum computing and AI. Microsoft and Quantinuum quantum computing researchers just ...

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 ...
