A Google-led research team has demonstrated a surface-code logical qubit operating below the error-correction threshold, ...

In the world of quantum computing, the Hilbert space dimension—the measure of the number of quantum states that a quantum computer can access—is a prized possession. Having a larger Hilbert space ...

The errors that quantum computers make are holding the technology back. But recent progress in quantum error correction has ...

Quantum error correction (QEC) and fault-tolerant computation provide the critical framework for realising reliable quantum processors in the presence of inevitable ...

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 ...

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 ...

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 ...
