Quantum hardware and software are advancing rapidly – and our online encryption systems need to change to stay ahead.

A University of Sydney quantum physicist has developed a new approach to quantum error correction that could significantly ...

“In quantum computers, information is transmitted and stored using so-called qubits (quantum bits). But quantum information ...

Most simplifies the complex process of quantum computing as "it can be 0 and 1 at the same time." That is not an explanation ...

Four different quantum systems with four different types of qubits were on display at Nvidia GTC, here's how they all work.

Quantum computers struggle with a major flaw: their information vanishes unpredictably. Scientists have now created a new method that can measure this loss over 100 times faster than before. By ...

Quantum computing could transform certain industries, but commercialization might be further off than investors think. Rigetti Computing has built some of the most accurate quantum systems to date, ...

Quantum circuits are supposed to gain power as they grow longer, but noise changes the picture. A new study finds that earlier steps in these circuits gradually lose their impact, with only the final ...

Research suggests Bitcoin users could defend against future quantum attacks using a transaction design that works within ...

When the commercial, scalable, fault-tolerant quantum computing era really begins, when it becomes widely available, it will – least at the start – be a cloud service that is integrated with classical ...

The performance of quantum computers could cap out after around 1,000 qubits, according to a new analysis published in the Proceedings of the National Academy of Sciences. Through new calculations, ...
