The quantum internet will arguably be the most important technological advancement of the 21st century. In the near-term, it will provide unparalleled information security and privacy. In the long-term, it will enable large-scale distributed quantum computing. However, to realize the advantages of the quantum internet we must overcome a key challenge: certifying the quantum capabilities of unknown, untrusted devices using only their input-output statistics. In this talk, we will apply the framework of general probabilistic theories to ascertain the physical distinction between quantum and classical devices. Then, we will discuss various device-independent tests which exploit these fundamental differences to certify quantum functionality. Finally, we will explore trust models in networked quantum devices and compare them to the familiar setting of electronic commerce.
