在实验室中对一个n量子比特态进行认证，以证明它与一个给定的目标态足够接近，是量子信息科学中的一项基础任务。然而，目前适用于通用目标态的严格协议，在资源需求上可能令人望而却步，因为它们要么需要深层量子线路，要么需要指数级数量的单量子比特测量。9月8日， ...

A survey of Scientific American’s century of quantum coverage helps explain the enduring popularity of strange physics ...

Made out of a fluorescent protein, the qubit is just 3 nanometers in diameter, scientists report August 20 in Nature. By hitting the protein with laser light, tweaking it with microwaves and observing ...

In March, D-Wave announced it performed a materials simulation using quantum technology. A few weeks later, Quantinuum published a paper in Nature detailing how it used the company’s six-qubit ...

For a century, quantum theory has passed every experimental test, but physicists can’t agree on how to use it to paint a picture of our reality – or even whether that is possible ...

Researchers have successfully used a quantum algorithm to solve a complex century-old mathematical problem long considered ...
