Composable free-space continuous-variable quantum key distribution using discrete modulation
Kevin Jaksch, Thomas Dirmeier, Yannick Weiser +16
Continuous-variable (CV) quantum key distribution (QKD) allows for quantum secure communication with the benefit of being close to existing classical coherent communication. In rec…
Towards Integrating True Random Number Generation in Coherent Optical Transceivers
Dinka Milovančev, Nemanja Vokić, Christoph Pacher +5
The integration of quantum communication functions often requires dedicated opto-electronic components that do not bode well with the technology roadmaps of telecom systems. We inv…
Agile and versatile quantum communication: signatures and secrets
Stefan Richter, Matthew Thornton, Imran Khan +7
Agile cryptography allows for a resource-efficient swap of a cryptographic core in case the security of an underlying classical cryptographic algorithm becomes compromised. Convers…
Distillation of Squeezing using a pulsed engineered PDC source
Thomas Dirmeier, Johannes Tiedau, Imran Khan +5
Hybrid quantum information processing combines the advantages of discrete and continues variable protocols by realizing protocols consisting of photon counting and homodyne measure…
Quantum-limited measurements of optical signals from a geostationary satellite
Kevin Günthner, Imran Khan, Dominique Elser +13
The measurement of quantum signals that traveled through long distances is of fundamental and technological interest. We present quantum-limited coherent measurements of optical si…
Evading Vacuum Noise: Wigner Projections or Husimi Samples?
Christian R. Müller, Christian Peuntinger, Thomas Dirmeier +8
The accuracy in determining the quantum state of a system depends on the type of measurement performed. Homodyne and heterodyne detection are the two main schemes in continuous-var…
