  Development of outreach skills is critical for researchers when communicating
their work to non-expert audiences. However, due to the lack of formal
training, researchers are typically unaware of the benefits of outreach
training and often under-prioritize outreach. We present a training programme
conducted with an international network of PhD students in quantum physics,
which focused on developing outreach skills and an understanding of the
associated professional benefits by creating an outreach portfolio consisting
of a range of implementable outreach products. We describe our approach, assess
the impact, and provide a list of guidelines for designing similar programmes
across scientific disciplines in the future.
