Benchmarking — Quiz

Test your understanding of benchmarking with 5 practice questions.

Practice Questions

Question 1

In the randomized benchmarking decay model $F(m)=A\,p^m+B$, what does the parameter $B$ represent?

Question 2

For a 3-qubit cross-entropy benchmarking experiment with average ideal output probability $\langle p_{\rm ideal}\rangle=0.10$, what is the linear XEB fidelity $F_{\mathrm{XEB}}=2^n\langle p_{\rm ideal}\rangle-1$?

Question 3

In volumetric benchmarking, what does the vertical axis represent on the performance plot?

Question 4

Which noise assumption underlies the exponential decay of fidelity in standard randomized benchmarking?

Question 5

In a standard RB experiment with $A=0.4$, $B=0.5$, and observed $F(20)=0.85$, what is the estimated depolarizing parameter $p$?
