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 ...

Quantum computers are computing systems that process information leveraging quantum mechanical effects. These computers rely ...

For more than a decade, the world of digital currency has been built on a single foundation: the blockchain. This complex, code-based system of distributed ledgers was a revolutionary approach to ...

Recent breakthroughs in quantum physics have unlocked extraordinary possibilities, reshaping not only the future of technology but also the potential for human evolution. One such milestone occurred ...

China is racing to harden its quantum ambitions on two fronts at once, pairing more powerful quantum processors with new ...

“The vision was to build a useful, large-scale quantum computer that could harness quantum mechanics — the ‘operating system’ of nature to the extent we know it today — to benefit society by advancing ...

For decades, quantum computing has been heralded as a technology of the future, promising to solve problems far beyond the reach of supercomputers. But its practical use has remained elusive.

Scientists have designed a physical qubit that behaves as an error-correcting "logical qubit," and now they think they can scale it up to make a useful quantum computer using a few hundred. When you ...
