Bell's 1964 theorem, which states that the predictions of quantum theory cannot be
accounted for by any local theory, represents one of the most profound developments in the …

Quantum correlations between two parties are essential for the argument of Einstein,
Podolsky, and Rosen in favor of the incompleteness of quantum mechanics. Schrödinger …

Quantum cryptography exploits principles of quantum physics for the secure processing of
information. A prominent example is secure communication, ie, the task of transmitting …

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 …

Quantum physics can be exploited to generate true random numbers, which have important
roles in many applications, especially in cryptography. Genuine randomness from the …

Device-independent quantum key distribution (DI-QKD) provides the gold standard for
secure key exchange. Not only does it allow for information-theoretic security based on …

The concept of randomness plays an important part in many disciplines. On the one hand,
the question of whether random processes exist is fundamental for our understanding of …

Device-independent cryptography goes beyond conventional quantum cryptography by
providing security that holds independently of the quality of the underlying physical devices …

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 …

Device-independent quantum key distribution (DIQKD) is information-theoretically secure
against adversaries who possess a scalable quantum computer and who have supplied …
