Security in quantum cryptography

C Portmann, R Renner - Reviews of Modern Physics, 2022 - APS
Quantum cryptography exploits principles of quantum physics for the secure processing of
information. A prominent example is secure communication, ie, the task of transmitting …

Quantum oblivious transfer: a short review

MB Santos, P Mateus, AN Pinto - Entropy, 2022 - mdpi.com
Quantum cryptography is the field of cryptography that explores the quantum properties of
matter. Generally, it aims to develop primitives beyond the reach of classical cryptography …

Embedding cyclic causal structures in acyclic spacetimes: no-go results for process matrices

V Vilasini, R Renner - ar** indefinite causal order processes to composable quantum protocols in a spacetime
M Salzger, V Vilasini - New Journal of Physics, 2024 - iopscience.iop.org
Formalisms for higher order quantum processes provide a theoretical formalisation of
quantum processes where the order of agents' operations need not be definite and acyclic …

A device-independent protocol for XOR oblivious transfer

S Kundu, J Sikora, EYZ Tan - Quantum, 2022 - quantum-journal.org
Oblivious transfer is a cryptographic primitive where Alice has two bits and Bob wishes to
learn some function of them. Ideally, Alice should not learn Bob's desired function choice …

Introduction to gravitational redshift of quantum photons propagating in curved spacetime

LAA Rodríguez, AW Schell… - Journal of Physics …, 2023 - iopscience.iop.org
Gravitational redshift is discussed in the context of quantum photons propagating in curved
spacetime. A brief introduction to modelling realistic photons is first presented and the effect …
