Experimental result for dishonest Alice and Bob. (a) Probability that Alice passes the tests of state tomography when Bob measures in X 1 X 2 Z 3 and Z 1 Z 2 Z 3 bases, if Alice deliberately reports the opposite results for the first qubit. (b) Probability that Alice passes the tests of state tomography when Bob measures in X 1 X 2 Z 3 and Z 1 Z 2 Z 3 bases, if Alice’s third measurement basis is X 3 instead of Z 3 . (c) Probability that Bob passes the tests of process tomography when Alice measures in Z 1 X 2 X 3 and Z 1 Z 2 Z 3 bases, if Bob measures the last two qubits in Z 2 Z 3 instead of the X 2 Z 3 basis. (d) Probability that Bob passes the tests of process tomography when Alice measures in Z 1 X 2 X 3 and Z 1 Z 2 Z 3 bases, if Bob’s first measurement basis is Z 1 instead of X 1 .
