Table 1 Performance of IBM’s quantum devices in our Elitzur–Vaidman bomb experiments. The averaged efficiency η for all machines are listed in the first row, differ from the theoretical efficiency \(\eta =1/3\). The absolute error is calculated as \(\vert \eta -1/3 \vert \), relative error is \(\frac{ \vert 1/3-\eta \vert }{1/3}\), and standard deviation is \(\sqrt{ \sum_{i=1}^{n}\frac{(\eta _{i}-\eta )^{2}}{n}}\), with n is the total number of runs and \(\eta _{i}\) is the efficiency of the ith run. Device error is calculated using the fidelity of a circuit, which is estimated as the product of fidelities of the circuit’s component gates. This information from IBM can be found in our Github [22] for the time that we ran these experiments
