Abstract
Magnetic resonance is a fundamental method to manipulate qubits in spin-based quantum information processing. In such areas, the functionality of fast frequency sweeping is required to determine the resonance of the system. We provide a hardware-synchronized sweeping microwave source with a minimal latency in the sub-μs level based on the direct digital synthesizer technique. The output frequency can be up-converted to match the requirement for particular applications. We demonstrate this module in an optically detected magnetic resonance experiment for a nitrogen-vacancy center, and the spectrum is obtained much faster than conventional schemes with high resolution. Comparing with commercial vector signal generators, our module is highly integrated on a single board with a limited area, especially suitable for engineering of quantum sensors and devices in the future.
