[Qmod Classiq-library function]

Implements an ansatz on a qubit array x with the given 1-qubit and 2-qubit operations.

The number of ansatz layers is given in argument reps. Each layer applies the 1-qubit operands in operands_1qubit to all the qubits in x. Next, it applies the 2-qubit operands in operands_2qubit to qubits (i, j) for each pair of indices (i, j) in connectivity_map.

The list is_parametrized specifies whether the operands in operands_1qubit and operands_2qubit are parametric (expect a classical argument). is_parametrized is a list of flags (0 and 1 integers) of length len(operands_1qubit) + len(operands_2qubit). The first len(operands_1qubit) flags refer to the operands_1qubit operands and the next len(operands_2qubit) flags refer to the operands_2qubit operands.

The classical arguments to the parametric operands are given in argument angle_params. angle_params concatenates a set of arguments for each ansatz layer. Each set contains an argument for each qubit in x times the number of parametric operands in operands_1qubit. These are followed by an argument for each mapping pair in connectivity_map times the number of parametric operands in operands_2qubit.
