In principle, quantum key distribution (QKD) offers information-theoretic security based on
the laws of physics. In practice, however, the imperfections of realistic devices might …

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

Heisenberg's uncertainty principle forms a fundamental element of quantum mechanics.
Uncertainty relations in terms of entropies were initially proposed to deal with conceptual …

Bit commitment is a fundamental cryptographic primitive in which Bob wishes to commit a
secret bit to Alice. Perfectly secure bit commitment between two mistrustful parties is …

We present a quantum position verification scheme in the random oracle model. In contrast
to prior work, our scheme does not require bounded storage/retrieval/entanglement …

Complex information-processing systems, for example, quantum circuits, cryptographic
protocols, or multi-player games, are naturally described as networks composed of more …

Bit commitment is a fundamental cryptographic primitive in which Alice wishes to commit a
secret bit to Bob. Perfectly secure bit commitment between two mistrustful parties is …

The goal of two-party cryptography is to enable two parties, Alice and Bob, to solve common
tasks without the need for mutual trust. Examples of such tasks are private access to a …

We investigate entropic uncertainty relations for two or more binary measurements, for
example, spin-1 2 or polarization measurements. We argue that the effective …
