Unconditionally Secure Commitment of a Certified Classical Bit is Impossible [PDF]

open access: yes, 1999
In a secure bit commitment protocol involving only classical physics, A commits either a 0 or a 1 to B. If quantum information is used in the protocol, A may be able to commit a state of the form $\alpha \ket{0} + \beta \ket{1}$.
