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 ...

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 ...

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 affiliated with Caltech and the quantum computing startup Oratomic have published a preprint claiming that Shor’s algorithm, the theoretical tool capable of breaking widely used public-key ...

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 ...
