The quantum bit commitment theorem
 Foundations of Physics 31: 735–756
, 2001
"... Unconditionally secure twoparty bit commitment based solely on the principles of quantum mechanics (without exploiting special relativistic signalling constraints, or principles of general relativity or thermodynamics) has been shown to be impossible, but the claim is repeatedly challenged. The qua ..."

Unconditionally secure twoparty bit commitment based solely on the principles of quantum mechanics (without exploiting special relativistic signalling constraints, or principles of general relativity or thermodynamics) has been shown to be impossible, but the claim is repeatedly challenged. The quantum bit commitment theorem is reviewed here and the central conceptual point, that an ``Einstein Podolsky Rosen' ' attack or cheating strategy can always be applied, is clarified. The question of whether following such a cheating strategy can ever be disadvantageous to the cheater is considered and answered in the negative. There is, indeed, no loophole in the theorem. 1.
Unconditionally Secure Quantum Bit Commitment Really Is Impossible
