Preserving Symmetries for Variational Quantum Eigensolvers in the Presence of Noise
Preserving Symmetries for Variational Quantum Eigensolvers in the Presence of Noise
One of the most promising applications of noisy intermediate-scale quantum computers is the simulation of molecular Hamiltonians using the variational quantum eigensolver. We show that encoding symmetries of the simulated Hamiltonian in the VQE ansatz reduces both classical and quantum resources compared to other, widely available ansatze. Through simulations of …
