"Our quantum error-correcting code has a greater than 1/2 code rate, targeting hundreds of thousands of logical qubits," explains Kasai. "Moreover, its decoding complexity is proportional to the ...

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 company said it is able to reduce error rates in its quantum computing capabilities by 1,000-fold thanks to four-dimensional geometric codes. Quantum Computing ...

Two-dimensional projection of a quantum spherical code composed of two copies (black and red) of the four complex dimensional Witting polytope. This code can correct up to five photon losses of any ...

Microsoft and Quantinuum say they’ve figured out how to make qubits that are less prone to error. Microsoft and Quantinuum say they’ve figured out how to make ...

Quantum computing may one day outperform classical machines in solving certain complex problems, but when and how this “quantum advantage” emerges has remained unclear. Now, researchers from Kyoto ...

Brookhaven Lab scientists with expertise in computational modeling and nuclear physics theory developed simulations to track quantum entanglement among secondary jets of particles emitted from ...

QUANTUM COMPUTERS, which exploit strange properties of the subatomic realm to crunch numbers in powerful new ways, do not actually work yet. But if and when they do start working, they will be able to ...

Classical computing has operated as the fundamental power behind our digital world for many decades. Modern civilization relies on classical systems to operate smartphones and global financial ...
