Anonymous transmission in a noisy quantum network using the <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mi>W</mml:mi></mml:math> state

2018 · Physical Review A

We consider the task of anonymously transmitting a quantum message in a network. We present a protocol that accomplishes this task using the $W$ state and we analyze its performance in a quantum network where …

Experimental anonymous quantum conferencing

2024 · Optica

Anonymous quantum conference key agreement (AQCKA) allows a group of users within a network to establish a shared cryptographic key without revealing their participation. Although this can be achieved using bipartite primitives alone, it is …

Quantum Key Distribution with Imperfections: Recent Advances in Security Proofs

2026 · Brazilian Journal of Physics

Abstract In contrast to classical public-key cryptosystems, where the security of encoded messages relies on computational assumptions, Quantum Key Distribution (QKD) enables two distant parties to establish a shared secret key that, when combined with …
