Scientists devloping novel technique that could facilitate nuclear disarmament: A proven system for verifying that apparent nuclear weapons slated to be dismantled contained true warheads could provide a key step toward the further reduction of nuclear arms. The system would achieve this verification while safeguarding classified information that could lead to nuclear proliferation.
Scientists at Princeton University and the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) are developing the prototype for such a system, as this week in Nature magazine. Their novel approach, called a "zero-knowledge protocol," would verify the presence of warheads without collecting any classified information at all.
"The goal is to prove with as high confidence as required that an object is a true nuclear warhead while learning nothing about the materials and design of the warhead itself," said physicist Robert Goldston, coauthor of the paper, a fusion researcher and former director of PPPL, and a professor of astrophysical sciences at Princeton.
