Abstract: A method of minimizing a cost function of a quantum computation is provided. The method comprises receiving input of an initial state of a quantum problem instance comprising a Hamiltonian with an associated cost function. The Hamiltonian is converted into a number of Pauli strings, which are used to form an operator pool. The Pauli strings in the operator pool are ranked according to how much they lower a value of the cost function with respect to the initial state. Pauli strings are iteratively added from the operator pool to a parameterized quantum circuit, in a manner to minimize circuit depth, until a variational quantum eigensolver (VQE) algorithm converges to an approximate ground state wave function generated by the parameterized quantum circuit.

Abstract: A method, apparatus, computer system, and computer program product for parallelizing quantum processes for processing a problem. A computer system identifies subproblems in the problem based on a structure of the problem. The computer system identifies quantum circuits in a set of quantum computers to process the subproblems. The computer system executes jobs on the quantum circuits to solve the subproblems.

Abstract: A method, apparatus, system, and computer program product for quantum processing. A target quantum programming for a process for a quantum computer is identified. A universal gate set is selected based on a computer type. Any operation possible for a particular quantum computer can be performed using the universal gate set. Instructions for the process in a source quantum programming language are sent to a source quantum language translator which outputs a digital model representation of quantum computer components that are arranged to perform the process using the instructions. The digital model representation of the quantum computer components and the universal gate set are sent to a target quantum language translator, which outputs the instructions for operations for the process in a target quantum programming language using the digital model representation of the quantum computer components and the universal gate set for the computer type for the quantum computer.
