Ever more optimized simulations of fermionic systems on a quantum computer
DescriptionNot unlike conventional computers, quantum computers work by implementing elementary gates. Among them, entangling gates are known to be most expensive. Here, a suite of compilation and optimization techniques that massively reduce the entangling-gate counts are studied, applicable for fermionic simulations. We exploit the well-studied classical optimization algorithms to achieve up to 24\% savings over the state of the art for several small-molecule simulations as examples. Our methodologies straightforwardly generalize to wider classes of near-term simulations of the ground state of a fermionic system or real-time simulations probing dynamical properties of a fermionic system.
