Cross-entropy benchmarking
text:
Cross-entropy benchmarking is a quantum benchmarking protocol which can be used to demonstrate quantum supremacy. In XEB, a random quantum circuit is executed on a quantum computer multiple times in order to collect a set of k samples in the form of bitstrings { x 1 , … , x k } . The bitstrings are then used to calculate the cross-entropy benchmark fidelity via a classical computer, given by where n is the number of qubits in the circuit and P is the probability of a bitstring x i for an ideal q
