LinearRotation

class LinearRotation(slope, offset, num_state_qubits, basis='Y', i_state=None, i_target=None)[source]

DEPRECATED. Linearly-controlled X, Y or Z rotation.

Deprecated since version 0.7.0: Use Terra’s qiskit.circuit.library.LinearPauliRotations instead.

For a register of state qubits |x> and a target qubit |0> this operator acts as:

|x>|0> –> |x>( cos(slope * x + offset)|0> + sin(slope * x + offset)|1> )

Parameters

  • slope (float) – slope of the controlled rotation

  • offset (float) – offset of the controlled rotation

  • num_state_qubits (int) – number of qubits representing the state

  • basis (str) – type of Pauli rotation (‘X’, ‘Y’, ‘Z’)

  • i_state (Optional(Union(list, numpy.ndarray))) – indices of the state qubits (least significant to most significant)

  • i_target (Optional(int)) – index of target qubit

Raises

ValueError – invalid input
