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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Co-authored by BTQ Chief Quantum Officer Dr. Gavin K. Brennen, the research introduces a new error-correction framework for permutation-invariant codes--an enabling step toward more reliable quantum ...

“We know how to make qubits work,” he says. “Now we see it as the engineering task to increase the number of qubits and reduce the noise.” And with a digital twin, researchers can experiment with ...
