This is a quantum algorithm that can be used to search an unsorted database of N items in O(√N) time. It is faster than classical algorithms, which require O(N) time to complete the same task. Developers can directly call the interface grover(arg1, arg2...) to support their user-defined algorithms.
The mixed HHL solver is an optimization of the HHL algorithm, which is mainly applied to solve large-scale linear equations, such as computational fluid dynamics.By using the "Krylov subspace" method to reduce the dimensionality of the original linear space and solving it with the HHL algorithm, it has a more stable solving performance and faster convergence rate.
VQE is a hybrid quantum-classical algorithm for computing the ground state energy of a Hamiltonian, which is one of the most promising algorithms applied in chemistry. Comparing to classical algorithms where computational costs grow exponentially to size of the system, the VQE algorithm increases polynomial in execution time of circuit and the number of measurement.
