Effects of coherence on temporal resolution
Syamsundar De, Jano Gil-Lopez, Benjamin Brecht +4
Measuring small separations between two optical sources, either in space or in time, constitute an important metrological challenge as standard intensity-only measurements fail for…
Raman Quantum Memory with Built-In Suppression of Four-wave Mixing Noise
Sarah E. Thomas, Thomas M. Hird, Joseph H. D. Munns +5
Quantum memories are essential for large-scale quantum information networks. Along with high efficiency, storage lifetime and optical bandwidth, it is critical that the memory add…
From quantum pulse gate to quantum pulse shaper -- enigneered frequency conversion in nonlinear optical waveguides
Benjamin Brecht, Andreas Eckstein, Andreas Christ +2
Full control over the spatio-temporal structure of quantum states of light is an important goal in quantum optics, to generate for instance single-mode quantum pulses or to encode…
Complementarity-based complementarity: the choice of mutually unbiased observables shapes quantum uncertainty relations
Laura Serino, Giovanni Chesi, Benjamin Brecht +3
Quantum uncertainty relations impose fundamental limits on the joint knowledge that can be acquired from complementary observables: perfect knowledge of a quantum state in one basi…
Certifying the Topology of Quantum Networks: Theory and Experiment
Lisa T. Weinbrenner, Nidhin Prasannan, Kiara Hansenne +5
Distributed quantum information in networks is paramount for global secure quantum communication. Moreover, it finds applications as a resource for relevant tasks, such as clock sy…
Probing spectral-temporal correlations with a versatile integrated source of parametric down-conversion states
Vahid Ansari, Benjamin Brecht, Georg Harder +1
The spectral-temporal correlation and the correlation time of a biphoton wavepacket generated in the process of parametric down-conversion (PDC), is of great importance for a broad…
