Researchers at ENS Lyon and ENS Paris-Saclay have demonstrated a tantalum-based transmon qubit that maintains stable charge offset for nearly three months—a significant finding for a field plagued by unpredictable charge drift that disrupts qubit operation.

The team, led by Benjamin Huard (ENS L...
