Abstract: We show that all proposed quantum bit commitment schemes are insecure because the sender can always cheat successfully by using an EPR-type of attack and delaying her measurement until she opens her commitment. PACS Numbers: 03.65.Bz, 89.70.+c, 89.80.+h Typeset using REVT E X e-mail: hkl@sns.ias.edu y e-mail: chau@sns.ias.edu A bit commitment scheme generally involves two parties, a sender, Alice and a receiver, Bob. Suppose that Alice has a bit (b = 0 or 1) in mind, to which she would... (Update)
