Linear cross entropy benchmark
Nettet5. mai 2024 · The linear cross-entropy benchmark (Linear XEB) has been used as a test for procedures simulating quantum circuits. Given a quantum circuit C with n inputs and outputs and purported simulator whose output is distributed according to a distribution p over {0,1}^n, the linear XEB fidelity of the simulator is ℱ_C (p) = 2^n 𝔼_x ∼ p q_C (x ...

Paper Digest Team analyzes all papers published on NIPS in the past years, and presents the 15 most influential papers for each year. 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

Nettetwhich is similar to the linear cross-entropy benchmark (“linear XEB”) for random unitary circuits [41, 42]. Then we discuss its limitations when applied to the MIPT and how to overcome them in case of a stabilizer circuit. A. General setup Consider running the circuit with initial state ⇢ (“the ⇢-circuit”) on a quantum simulator. NettetA scalable (in the number n n of qubits comprising the system) and robust algorithm for benchmarking the full set of Clifford gates by a single parameter using randomization techniques was presented in [1]. The concept of using randomization methods for benchmarking quantum gates is commonly called Randomized Benchmarking (RB).
