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 ...

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 ...

Google successfully used quantum error correction in practice, opening the door to large quantum computers with vast capabilities. The team used a surface code to ...

Scientists at the Institute of Science Tokyo have announced a breakthrough in quantum error correction that could bring a large-scale quantum computer closer to ...

On Tuesday, Microsoft made a series of announcements related to its Azure Quantum Cloud service. Among them was a demonstration of logical operations using the largest number of error-corrected qubits ...

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 ...

In a scene from the movie Gladiator, Roman emperor Marcus Aurelius, worried about the fragility of his empire, tells his general, Maximus: “There was once a dream that was Rome. You could only whisper ...

There is no shortage of top-name – and even lesser known – companies pursuing the white whale of developing a quantum computer that can run workloads and solve problems that today’s most powerful ...

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 ...

The realisation of a large-scale fault tolerant quantum computer is a central goal of quantum information science. While theoretical work has long suggested that this goal is achievable, the ...
