12. B] = a→ · b̄, which cannot be obtained by direct measurement in quantum physics (the corresponding "density matrix" would have negative eigenvalues on some entangled states), but that, can be easily produced in the lab by assuming that Bob systematically flips his result. Anyway, this is a more general point: the procedures for simulation of entanglement known to date have no a priori derivation, but are legitimated a posteriori by the fact, that they recover the desired correlations.

31. This is the reason why, one day in April 2005, two papers were posted on the ArXiV server supporting apparently opposite conclusions: H. Buhrman, M. Christandl, F. Unger, S. Wehner, A. Winter, quant-ph/0504133;
32. and T. Short, N. Gisin, S. Popescu, quant-ph/0504134. The authors of the first paper claimed bit commitement to be possible because they trusted the presence of a true PR-box in the OT; the authors of the second claimed it impossible, because they did not accept trusting it.
