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 ...

Ripples spreading across a calm lake after raindrops fall—and the way ripples from different drops overlap and travel outward ...

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

SHERBROOKE, Canada (February 8 th, 2024) – Nord Quantique, a quantum computing startup with an industry leading approach to error correction, today announced ...

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 ...

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 ...

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 ...

Error Correction Codes (ECC) play an essential role in safeguarding memory systems by detecting and correcting errors that arise from various sources, including ...

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 ...
