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

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 ...

One paper finds that attacking the bitcoin blockchain through quantum mining would demand the energy output of a star.

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

XRP’s design leaves a smaller share of its supply exposed to future quantum attacks than Bitcoin’s, experts said, pointing to ...

Quantum computers promise to revolutionize whole industries by outperforming classical computers on complex calculations. They just need to be colder than the coldest natural place in the universe.

Quantum computing breaktrhroughs including new hardware, smarter algorithms, and clearer signs of “quantum advantage,” bring ...

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, ...

Looking through a window with 'hardware lab' written in white text on the glass. Inside the room beyond the glass is a man sitting on an office chair working at a computer. His workbench is on the ...

A small mathematical revision to quantum mechanics could effectively limit the purported infinite capacities of quantum computers—if validated, that is. Reading time 3 minutes The entire spiel of ...

Charles H. Bennett and Gilles Brassard, winners of this year’s Turing Award, spent their lives touting the advantages of the ...

Nvidia said quantum computing will complement rather than replace GPUs, even as Taiwan accelerates investment in quantum technology. Speaking at an industry event, the company said it does not expect ...
