FAYETTEVILLE, Ark. — Because error correction will generate more energy than chips can dissipate, quantum computers may be further off than previously believed ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists at the Institute of Science Tokyo have announced a breakthrough in quantum error ...

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 ...

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 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 ...

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team has developed a method ...

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 ...

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 ...

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 ...
