Superconducting qubits achieve a new record coherence time of 1 millisecond.

The University of Aalto in Finland announced on the 8th that their researchers have extended the coherence time of superconducting quantum bits to 1 millisecond, setting a new record in the field of quantum science. According to the news release from the university, the previously known record for the longest coherence time of quantum bits was close to 0.6 milliseconds, while the team at Aalto University measured a coherence time of 1 millisecond, with a median of 0.5 milliseconds. The research results have been published in the journal Nature Communications in the UK.
