Quantum computing is expected to leave classical computing in the dust when it comes to solving some of the world’s most fiendishly difficult problems. The best quantum machines today have one major ...

Quantum computing breakthroughs from IonQ, D-Wave, QuEra, Alice & Bob, and others in the last six months, with dates, achievements, and their impact on error-corrected, scalable quantum systems. May 7 ...

Ripples spreading across a calm lake after raindrops fall—and the way ripples from different drops overlap and travel outward—is one image that helps us picture how a quantum computer handles ...

These novel error-correction codes can handle quantum codes with hundreds of thousands of qubits, potentially enabling large-scale fault-tolerant quantum computing, with applications in diverse fields ...

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 ...
