Unconditionally secure quantum bit commitment (QBC) was consideredimpossible. But the no-go proofs are based on the Hughston-Jozsa-Wootters (HJW)theorem (a.k.a. the Uhlmann theorem). Recently it was found that inhigh-dimensional systems, there exist some states which can display a chaoseffect in quantum steering, so that the attack strategy based on the HJWtheorem has to require the capability of discriminating quantum states withvery subtle difference, to the extent that is not allowed by the uncertaintyprinciple. With the help of this finding, here we propose a simple QBC protocolwhich manages to evade the no-go proofs.
