Nettet3. des. 2024 · It has been suggested that this approach can be certified with the Linear Cross-Entropy Benchmark (XEB). We critically examine this notion. First, in a "benign" setting where an honest implementation of noisy quantum circuits is assumed, we characterize the conditions under which the XEB approximates the fidelity. Nettet11. apr. 2024 · We trained and evaluated our model on Benchmark 4.0 based on the 5-fold cross-validation. As the representatives of physical energy/knowledge-based, machine leaning-based, and deep learning-based approaches, ZDOCK, GNN-DOVE, our previously proposed DGANN-based algorithms and TRScore were also tested on this …
Nettet9. aug. 2024 · the benchmarking method used in this paper is called cross entropy benchmarking (XEB). An example circuit implementation for a 5 qubit XEB sequence is shown in fig. 3 of the paper. For further info, I recommend looking at the supplementary information (SI) of this paper, particularly fig. S15. Cross-entropy benchmarking (also referred to as XEB) is 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 samples in the form of bitstrings . The bitstrings are then used to calculate the cross-entropy benchmark fidelity () via a classical computer, given by
