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

Quantum computers, systems that process information leveraging quantum mechanical effects, could soon outperform classical computers on some complex computational problems. These computers rely on ...

On Tuesday, the quantum computing startup Quera laid out a road map that will bring error correction to quantum computing in only two years and enable useful ...

Quantum is smart. The progression toward embryonic quantum computing services represents a shift (you know what kind) in terms of the amount of intelligence we can apply to computing, data analytics ...

Error-corrected magic: Clifford circuits attain universality – that is, the ability to compute any function that quantum theory permits – upon injection of special states called magic states.

Surface code: illustration of how error correction works for bit and phase flips. The measure qubits on light blue backgrounds check for phase flip errors while the ...

That’s why the field is racing to develop and implement quantum error-correction (QEC) schemes to alleviate the technology’s inherent unreliability. These approaches involve building redundancies into ...

As memory bit cells of any type become smaller, bit error rates increase due to lower margins and process variation. This can be dealt with using error correction to ...

Some observers have hailed the response to Covid-19 as a triumph for science. A hesitant triumph, perhaps. Full of missteps and recriminations, frustrations and death. Maybe more a hard-won victory.
