Function quantumFourierTransform

quantumFourierTransform(
    circuit: Circuit,
    startQubit?: number,
    numQubits?: number,
    inverse?: boolean,
): void
Applies the Quantum Fourier Transform (QFT) or its inverse to a set of qubits within a circuit.

The QFT is a linear transformation on quantum bits, and is the quantum analogue of the discrete Fourier transform.
Parameters
- circuit: Circuit
  The quantum circuit to which the QFT will be applied.
- startQubit: number = 0
  The index of the first qubit in the register to apply QFT to. Defaults to 0.
- OptionalnumQubits: number
  The number of qubits to include in the QFT. Defaults to all qubits from startQubit.
- inverse: boolean = false
  If true, applies the inverse QFT. Defaults to false.
Returns void
Throws
If the specified qubit range is invalid.
