HEIFEI -- Chinese scientists have developed a programmable quantum computing prototype called "Jiuzhang 4.0" that has set a new world record for optical quantum information technology, according to a ...

For the past decade, quantum computing has struggled to balance promise and practicality. While the world’s most advanced systems remain engineering marvels, they’re bedeviled by the same flaw: the ...

Quantum Art's new QPU could be both significantly smaller and also faster than competing quantum architectures. How can we reinvent quantum computing? Perhaps by shrinking it down and making it small: ...

"Our nonlinear system transmits quantum information with 94% fidelity, compared to the theoretical limit of 33% on systems using linear optical components," said Kejie Fang, an Illinois professor of ...
