In a pair of papers submitted June 17 at arXiv.org, researchers generated conditions called “magic states,” crucial components of quantum computations. And those magic states were high-quality enough ...

You can implement FEC techniques for linear block codes (Reed-Solomon codecs) and convolutional codes (Viterbi codecs). To understand this general implementation, look at the hardware behind these ...

This makes the correction method a “key milestone,” according to Nord Quantique. It’s billed as particularly appealing to high-performance computing (HPC) data centre operators concerned about space ...

In this setup, they introduced fault-tolerant code-switching between two different codes and prepared 12 distinct logical states that cannot be supported by a single correction code.

How it works: Surface code logical qubits for processors of increasing size. Each larger processor can correct more errors than its predecessor. The encoded quantum state is stored on the array of ...

Google’s new chip, Willow, has achieved the exponential suppression of errors. The advance is substantial, but Willow remains far from delivering on any practical applications ...

This paper considers a novel error-correcting scheme exploiting chaotic dynamics for noncoherent chaos communication. In our proposed system, two successive chaotic sequences are generated from the ...

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.

Three startups have announced error-correction breakthroughs that could accelerate enterprise adoption of quantum computing. Topics Spotlight: New Thinking about Cloud Computing ...
