Trotter–Suzuki product formulas
Trotter–Suzuki product formulas, also called Trotterization, approximate the exponential of a sum of operators as a product of exponentials and are the most common quantum simulation method.
Ultracold atom quantum simulation
Ultracold atom quantum simulation uses laser-trapped gases of atoms cooled to near absolute zero to mimic quantum systems too complex to calculate or measure directly, following Feynman's 1982 proposal.
Variational quantum eigensolver
The variational quantum eigensolver (VQE) is a hybrid quantum-classical algorithm, introduced by Alberto Peruzzo and Jarrod McClean's team, that estimates ground-state energies by optimizing a parameterized quantum state with a classical optimizer.
Verification and benchmarking of quantum simulators
Verification and benchmarking of quantum simulators are methods for checking that a quantum simulator's output matches its target model, using fidelity estimation, accreditation protocols, and classical cross-checks.
