Quantum imaging attempts to exploit the quantum features of light in order to enhance one or more aspects of classical imaging. Here we focus on two quantum imaging schemes - ghost imaging and interaction-free imaging - and moreover, on their combination. After a brief overview of the subject we report the main result: a laboratory demonstration of a new imaging scheme termed Interaction-Free Ghost Imaging. We then explain its merits for the task of imaging various structured objects. Next, we discuss an outgrowth of this scheme used for the purpose of nonlocal quantum erasure. We conclude by mentioning some related, low-dose schemes (both quantum and quantum-inspired) for X-ray and gammaray sources.
