A new report by Capgemini warns that quantum computing may break the widely used public-key cryptographic systems within the next decade — threatening everything from online banking to blockchain ...

Scientists have recently unveiled a groundbreaking quantum bit, or qubit, design that promises to revolutionize quantum computing. This new development could significantly enhance the stability and ...

Google claims to have developed a quantum computer algorithm that is 13,000 times faster than the most powerful supercomputers. This would bring the technology another step closer to real-world ...

Quantum computers still can’t do much. Almost every time researchers have found something the high-tech machines should one day excel at, a classical algorithm comes along that can do it just as well ...

Quantum technology can process an enormous amount of data and solve complex problems in seconds rather than decades. Remarkably, quantum technology first appeared in the early 1900s. It originated ...

Although quantum computing is a nascent field, there are plenty of key moments that defined it over the last few decades as scientists strive to create machines that can solve impossible problems.
