This is a list of papers and publications that I have participated in. My work can be divided roughly into two topics, so the publications are listed separately under these two.

Anonymous conference key agreement

1. Anonymous Conference Key Agreement (arxiv, Published)

Hahn, de Jong, Pappa - Anonymous Conference Key Agreement. PRX Quantum 1, 020325 (2020).

  • The first proof of concept for anonymous conference key agreement (ACKA) in quantum networks.

2. Anonymous and secret communications in quantum networks (arxiv, Published)

Thalacker, Hahn, de Jong, Pappa, Barz - New J. Phys. 23 083026 (2021).

  • Experimental realization of the first ACKA protocol.

3. Secure Anonymous Conferencing in Quantum Networks (arxiv, Published)

Grasselli, Murta, de Jong, Hahn, Bruß, Kampermann, Pappa - PRX Quantum 3, 040306 (2022).

  • An improved ACKA protocol that is both robust and more secure. Includes finite key analysis and simulations.

4. Anonymous conference key agreement in linear quantum networks (arxiv, Published)

de Jong, Hahn, Eisert, Walk, Pappa - Quantum 7, 1117 (2023).

  • An ACKA protocol that uses linear networks, which are much easier to realize than the central networks of the previous protocols.

5. Experimental ACKA using linear cluster states (arxiv, Published)

Rückle, Budde, de Jong, Hahn, Pappa, Barz - Phys. Rev. Research 5, 033222 (2023).

  • Experimental realization of the ACKA protocol in linear networks.

Entanglement in networks and graph states

1. Extracting GHZ states from linear cluster states (arxiv, Published)

de Jong, Hahn, Tcholtchev, Hauswirth, Pappa - Phys. Rev. Research 6, 013330 (2023).

  • A complete characterization of how GHZ states can be realized from linear cluster states in quantum networks.

2. Distinguishing graph states by the properties of their marginals (arxiv)

Vandré*, de Jong*, Hahn, Burchardt, Gühne, Pappa - arxiv preprint. * these authors have contributed equally.

  • A study on how to detect distinguish different forms of entanglement in quantum networks by using the properties of reduced states.
