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 …

The ability to control multidimensional quantum systems is central to the development of
advanced quantum technologies. We demonstrate a multidimensional integrated quantum …

High-dimensional encoding of quantum information provides a way of transcending the
limitations of current approaches to quantum communication, which are mostly based on the …

Nonlocality was discovered by John Bell in 1964, in the context of the debates about
quantum theory, but is a phenomenon that can be studied in its own right. Its observation …

The concept of self-testing (or rigidity) refers to the fact that for certain Bell inequalities the
maximal violation can be achieved in an essentially unique manner. In this work we present …

Certifying quantum properties with minimal assumptions is a fundamental problem in
quantum information science. Self-testing is a method to infer the underlying physics of a …

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 …

Mutually unbiased bases (MUBs) and symmetric informationally complete projectors (SICs)
are crucial to many conceptual and practical aspects of quantum theory. Here, we develop …

Bipartite and multipartite entangled states are of central interest in quantum information
processing and foundational studies. Efficient verification of these states, especially in the …

Bell inequalities play a key role in certifying quantum properties for device-independent
quantum information protocols. It is still a major challenge, however, to devise Bell …
