Figure 1: Honest and cheating states of the loss-tolerant protocol.

From: Experimental loss-tolerant quantum coin flipping

Figure 1

The states used are represented on a great circle on the Bloch sphere. (a) BB84 states, corresponding cheating states |A0> and |A1> for Alice, equal to with ϕA=67.5°, and corresponding cheating states |B0> and |B1> for Bob, equal to with ϕB=22.5°. (b) Fair states and the corresponding cheating states defined as for the BB84 states but with ϕA≈63.4° and ϕB≈18.4°.
