Systems and methods for generating a coherent matterwave beam are provided. In some aspects, a system includes a plurality of beam generating units. Each of the plurality of beam generating units is configured to generate a stream of charged particles. The system also includes a magnetic field generator configured to expose the plurality of streams to a magnetic field such that (i) the charged particles of the plurality of streams undergo phase synchronization with one another in response to a vector potential associated with the magnetic field and (ii) the plurality of streams is directed along one or more channels to combine with one another and produce a coherent matterwave beam.
