Quantum Computer Apparatus and Method for Operation

Abstract

There is provided a hybrid computing arrangement this is configured to implement a simulation of a chemical system, wherein the hybrid computing arrangement includes a combination of a classical computer coupled to a quantum computer, wherein the hybrid computing arrangement is configured in use to receive input data and to generate corresponding processed output data from the input data, wherein the computing arrangement is: (a) configured to receive information describing a chemical system in the input data: (b) configured to process the information describing the chemical system using a pre-entangler algorithm and a fixed circuit algorithm to generate a quantum ansatz defining initial values for a quantum circuit computation, and a Hamiltonian from which is generated a variational circuit algorithm: (c) configured to compute using the quantum ansatz and the variation circuit algorithm a corresponding quantum circuit to generate quantum computations results; and (d) configured to process the quantum computational results to generate the output data including information describing an electron orbital simulation of the chemical system.
