qp.labs.estimator_beta.hadamard_toffoli_based_controlled_decomp¶

hadamard_toffoli_based_controlled_decomp(num_ctrl_wires, num_zero_ctrl, target_resource_params=None)[source]¶

Returns a list representing the resources for a controlled version of the Hadamard operator.

Note

This operation assumes a catalytic T state is available. Users should ensure the cost of constructing such a state has been accounted for.

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 | None) – A dictionary containing the resource parameters of the target operator.

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]
