According to the U.S. Department of State, the statement promoted increased engagement through international conferences and events, supported joint efforts to prepare the next generation of quantum scientists and engineers, and encouraged sharing of research methodologies, infrastructure, and data. It was the first international quantum cooperation statement to reflect principles of the Joint Committee on the Research Environment.
