braket.experimental.algorithms.quantum_fourier_transform.quantum_fourier_transform.quantum_fourier_transform_circuit(num_qubits: int) → Circuit[source]

Construct a circuit object corresponding to the Quantum Fourier Transform (QFT) algorithm, applied to the argument qubits. Does not use recursion to generate the QFT.

Parameters:

num_qubits (int) – number of qubits on which to apply the QFT

Returns:

Circuit – qft circuit

braket.experimental.algorithms.quantum_fourier_transform.quantum_fourier_transform.qft(qubits: Qubit | int | Iterable[Qubit | int]) → Circuit[source]

Add qft circuit to an existing circuit.

Parameters:

qubits (QubitSetInput) – The list of qubits labels on which to apply the QFT

Returns:

Circuit – qft circuit

braket.experimental.algorithms.quantum_fourier_transform.quantum_fourier_transform.inverse_quantum_fourier_transform_circuit(num_qubits: int) → Circuit[source]

Construct a circuit object corresponding to the inverse Quantum Fourier Transform (QFT) algorithm, applied to the argument qubits. Does not use recursion to generate the circuit.

Parameters:

num_qubits (int) – number of qubits on which to apply the inverse QFT

Returns:

Circuit – inverse qft circuit

braket.experimental.algorithms.quantum_fourier_transform.quantum_fourier_transform.iqft(qubits: Qubit | int | Iterable[Qubit | int]) → Circuit[source]

Add inverse qft circuit to an existing circuit.

Parameters:

qubits (QubitSetInput) – The list of qubits labels on which to apply the IQFT

Returns:

Circuit – inverse qft circuit
