There are some obvious big picture issues that stand between us and useful quantum computing. Issues like whether we can make ...

Error-correcting codes defined over finite fields form the cornerstone of reliable digital communication and data storage. Such codes exploit the algebraic structure of finite fields—denoted GF(q)—to ...

Error-correcting codes form the cornerstone of reliable modern communications, ensuring that digital information survives noise, interference and channel imperfections. Building on Shannon’s channel ...

Computers also make mistakes. These are usually suppressed by technical measures or detected and corrected during the calculation. In quantum computers, this involves some effort, as no copy can be ...

When running a server, especially one with mission-critical applications, it’s common practice to use error-correcting code (ECC) memory. As the name suggests, it uses an error-correcting algorithm to ...

IQM Quantum Computers has developed a new quantum error-correcting code that it says can reduce logical error rates by up to 1,000 times compared with the widely used ...

The research, available on arXiv, and co-authored by IQM researchers and collaborators at Freie Universität Berlin, the University of Edinburgh, and Johannes Gutenberg-Universität Mainz, introduces ...

Quantum computing is still in its infancy, easily beaten by traditional computers. One of the biggest challenges? The fact that quantum bits — qubits — are much more fragile than the bits in silicon ...

IQM Quantum Computers, the global leader in superconducting quantum computers, has developed a novel quantum error-correcting ...

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 ...
