Quantum cryptography is the art and science of exploiting quantum mechanical effects in
order to perform cryptographic tasks. While the most well-known example of this discipline is …

Timed-release encryption is a kind of encryption scheme in which a recipient can decrypt
only after a specified amount of time T (assuming that we have a moderately precise …

Consider an abstract storage device Σ(G) that can hold a single element x from a fixed,
publicly known finite group G. Storage is private in the sense that an adversary does not …

Algebraic manipulation detection codes are a cryptographic primitive that was introduced by
Cramer et al.(Eurocrypt 2008). It encompasses several methods that were previously used in …

We develop a framework for learning properties of quantum states beyond the assumption of
independent and identically distributed (iid) input states. We prove that, given any learning …

Users of quantum networks can securely communicate via so-called (quantum) conference
key agreement—making their identities publicly known. In certain circumstances, however …

Superposition of two or more states is one of the most fundamental concepts of quantum
mechanics and provides a basis for several advantages offered by quantum information …

Anonymity is a desirable yet challenging requirement of communication networks. In this
paper, we present the first quantum anonymous notification (QAN) protocol that introduces …

The fundamental properties of quantum information and its applications to computing and
cryptography have been greatly illuminated by considering information-theoretic tasks that …

Networks of quantum sensors are a central application of burgeoning quantum networks. A
key question for the use of such networks will be their security, particularly against malicious …
