Self-testing is a method to infer the underlying physics of a quantum experiment in a black
box scenario. As such it represents the strongest form of certification for quantum systems. In …

Applications of quantum technology often require fidelities to quantify performance. These
provide a fundamental yardstick for the comparison of two quantum states. While this is …

Quantum technologies promise advantages over their classical counterparts in the fields of
computation, security and sensing. It is thus desirable that classical users are able to obtain …

The goal of self-testing is to characterize an a priori unknown quantum system based solely
on measurement statistics, ie, using an uncharacterized measurement device. Here we …

The network structure offers in principle the possibility for novel forms of quantum nonlocal
correlations, that are proper to networks and cannot be traced back to standard quantum …

Device-independent quantum key distribution provides security even when the equipment
used to communicate over the quantum channel is largely uncharacterized. An experimental …

Self-testing represents the strongest form of certification of a quantum system. Here, we
theoretically and experimentally investigate self-testing of nonprojective quantum …

Bell inequalities constitute a key tool in quantum information theory: they not only allow one
to reveal nonlocality in composite quantum systems, but, more importantly, they can be used …

Distributed quantum information in networks is paramount for global secure quantum
communication. Moreover, it finds applications as a resource for relevant tasks, such as …

Mutually unbiased bases (MUBs) constitute the canonical example of incompatible quantum
measurements. One standard application of MUBs is the task known as quantum random …
