Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team has developed a method ...

Imagine the tiniest game of checkers in the world—one played by using lasers to precisely shuffle around ions across a very small grid. That's the idea behind a recent study published in the journal ...

A Google-led research team has demonstrated a surface-code logical qubit operating below the error-correction threshold, showing that logical errors can fall rapidly as the code scales up. The ...
