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…
Free-space quantum signatures using heterodyne detection
Callum Croal, Christian Peuntinger, Bettina Heim +6
Digital signatures guarantee the authorship of electronic communications. Currently used "classical" signature schemes rely on unproven computational assumptions for security, whil…
