The post-processing of quantum key distribution mainly includes error correction and privacy amplification. The error correction algorithms and privacy amplification ...

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 ...

"We're at a point where theory and experiment are beginning to align," Dr. Williamson said. "The big question now is how to design quantum computers that can be scaled efficiently to solve useful ...

Nvidia and Infleqtion have announced new breakthrough. Infleqtion, a world leader in neutral atom quantum computing, used the NVIDIA CUDA-Q platform to first simulate, and then orchestrate the ...

Quantum computing news usually picks up near the end of the year, as companies try to provide evidence that they are hitting ...

Two quantum information theorists have solved a decades-old problem that will free up quantum computing power. University of Sydney quantum researchers Dominic Williamson and Nouédyn Baspin have ...

Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

Researchers from the University of Sydney, working with IBM, have identified and quantified important factors limiting the ...

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 ...

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 ...

For the first time, a quantum computer has improved its results by repeatedly fixing its own mistakes midcalculation with a technique called quantum error correction ...
