The physical layer, being the lowest level of the communication stack, has increasingly been recognised as a locus for both encryption and error correction. Physical ...

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 ...

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 ...

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 ...

Caltech and Oratomic researchers have proposed a design showing that a quantum computer capable of breaking RSA-2048 encryption could be built with only 10,000–20,000 physical qubits, instead of 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 ...

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 ...

Researchers at Caltech and Oratomic have developed a quantum error-correction architecture that slashes the number of qubits needed for fault-tolerant computing from millions to as few as ...
