UncertaintyProblem

class UncertaintyProblem(num_qubits)

GitHub

The abstract Uncertainty Problem component.


Attributes

num_target_qubits

Returns the number of target qubits


Methods

build

abstract UncertaintyProblem.build(qc, q, q_ancillas=None, params=None)

Adds corresponding sub-circuit to given circuit

Parameters

  • qc (QuantumCircuit) – quantum circuit
  • q (list) – list of qubits (has to be same length as self._num_qubits)
  • q_ancillas (list) – list of ancilla qubits (or None if none needed)
  • params (list) – parameters for circuit

build_controlled

UncertaintyProblem.build_controlled(qc, q, q_control, q_ancillas=None, use_basis_gates=True)

Adds corresponding controlled sub-circuit to given circuit

Parameters

  • qc (QuantumCircuit) – quantum circuit
  • q (list) – list of qubits (has to be same length as self._num_qubits)
  • q_control (Qubit) – control qubit
  • q_ancillas (list) – list of ancilla qubits (or None if none needed)
  • use_basis_gates (bool) – use basis gates for expansion of controlled circuit

build_controlled_inverse

UncertaintyProblem.build_controlled_inverse(qc, q, q_control, q_ancillas=None, use_basis_gates=True)

Adds controlled inverse of corresponding sub-circuit to given circuit

Parameters

  • qc (QuantumCircuit) – quantum circuit
  • q (list) – list of qubits (has to be same length as self._num_qubits)
  • q_control (Qubit) – control qubit
  • q_ancillas (list) – list of ancilla qubits (or None if none needed)
  • use_basis_gates (bool) – use basis gates for expansion of controlled circuit

build_controlled_inverse_power

UncertaintyProblem.build_controlled_inverse_power(qc, q, q_control, power, q_ancillas=None, use_basis_gates=True)

Parameters

  • qc (QuantumCircuit) – quantum circuit
  • q (list) – list of qubits (has to be same length as self._num_qubits)
  • q_ancillas (list) – list of ancilla qubits (or None if none needed)

build_inverse_power

UncertaintyProblem.build_inverse_power(qc, q, power, q_ancillas=None)

Adds inverse power of corresponding circuit. May be overridden if a more efficient implementation is possible

build_power

UncertaintyProblem.build_power(qc, q, power, q_ancillas=None)

Adds power of corresponding circuit. May be overridden if a more efficient implementation is possible
