We discuss quantum key distribution protocols and their security analysis, considering a
receiver-device-independent (RDI) model. The sender's (Alice's) device is partially …

We consider networks featuring preparation, transformation, and measurement devices, in
which devices exchange communication via mediating physical systems. We investigate the …

Random numbers are essential for multiple applications, including cryptography, financial
security, digital rights management and scientific simulations. However, producing random …

Device and semi-device-independent private quantum randomness generators are crucial
for applications requiring private randomness. However, they are vulnerable to detection …

In this paper, we analyze several critical issues in semi-device-independent quantum
information processing protocol. In practical experimental realization, randomness …

How to generate genuine quantum randomness from untrusted devices is an important
problem in quantum information processing. Inspired by previous work on a self-testing …

Quantum systems can be used to certify the existence of true randomness in nature, and
semi-device-independent (SDI) randomness expansion has been used to achieve this goal …
