Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

Scientists map how quantum computer errors persist and link over time, revealing hidden memory that could reshape error ...

"In this way, the quantum computer can switch to the second code whenever a logic gate that is difficult to realize appears in the first code. This makes it easier to implement all the gates required ...

Researchers at USTC in China turned to microwave-based error correction to achieve a distance-7 logical qubit, much like ...

Physicists are quietly rolling out a new generation of simulation codes that promise to do more than crunch numbers. By ...

A library of computer code developed for quantum interactions can be used on problems from modeling the flow of electrons to predicting the price of copper in a stock market. (Illustration: Purdue ...

For nearly a century, some of the strangest questions in physics have revolved around how quantum objects move, interact and ...
