selectpaulirot_controlled_resource_decomp(num_ctrl_wires, num_zero_ctrl, target_resource_params)

Returns a list representing the resources of the controlled version of the SelectPauliRot operator. Each object in the list represents a gate and the number of times it occurs in the circuit.

Parameters:

• num_ctrl_wires (int) – the number of qubits the operation is controlled on

• num_zero_ctrl (int) – the number of control qubits, that are controlled when in the \(|0\rangle\) state

• target_resource_params (dict) – A dictionary containing the resource parameters of the target operator.

Resources:

The resources are obtained from the construction scheme given in Möttönen and Vartiainen (2005), Fig 7a. Specifically, the resources for an \(n\) qubit unitary are given as \(2^{n}\) instances of the CNOT gate and \(2^{n}\) instances of the controlled single qubit rotation gate (RX, RY or RZ) depending on the rot_axis.

Returns:

A list of GateCount objects, where each object represents a specific quantum gate and the number of times it appears in the decomposition.

Return type:

list[GateCount]
