    "abstract": "Using unstable particles which decay by emitting neutrinos, we propose a\nquantum bit commitment protocol that is humanly impossible to break. Neutrinos\ncarry away quantum information, but their interaction with matter is so weak\nthat it would take an astronomically-sized machine just to catch them, not to\nmention performing controlled unitary operations on them. As a result quantum\ninformation is lost, and cheating is not possible even if the participants had\naccess to the most powerful quantum computers that could ever be built.\nTherefore, for all practical purposes, our new protocol is as good as\nunconditionally secure.",
