One small qubit, one giant leap for quantum computing (www.sciencedaily.com)

Aalto University physicists in Finland have set a new benchmark in quantum computing by achieving a record-breaking millisecond coherence in a transmon qubit — nearly doubling prior limits. This development not only opens the door to far more powerful and stable quantum computations but also reduces the burden of error correction.

How many times did they do this?

They made >10,000 attempts and reported the average.

You can see their graphs in the Nature journal article:
