The shape created had those same qualities regardless of the qubit’s starting position, meaning that the complex waveforms created by a single qubit’s behaviors over time and within space did ...

But there are several other elements of qubit architecture that could also affect coherence times. For example, when a qubit is exposed to air, the surface-level tantalum reacts with oxygen.

Fujitsu and RIKEN (a leading Japanese research institute) have announced that they’ve developed a new 256-qubit superconducting quantum computer, which significantly expands their quantum ...
