Highly efficient frequency conversion with bandwidth compression of quantum light
Markus Allgaier, Vahid Ansari, Linda Sansoni +5
Hybrid quantum networks rely on efficient interfacing of dissimilar quantum nodes, since elements based on parametric down-conversion sources, quantum dots, color centres or atoms…
Extracting the physical sector of quantum states
Dmitri Mogilevtsev, Yong-Siah Teo, Jaroslav Rehacek +6
The physical nature of any quantum source guarantees the existence of an effective Hilbert space of finite dimension, the physical sector, in which its state is completely characte…
Tomography and Purification of the Temporal-Mode Structure of Quantum Light
Vahid Ansari, John M. Donohue, Markus Allgaier +6
High-dimensional quantum information processing promises capabilities beyond the current state of the art, but addressing individual information-carrying modes presents a significa…
Discorrelated quantum states
Evan Meyer-Scott, Johannes Tiedau, Georg Harder +2
The statistical properties of photons are fundamental to investigating quantum mechanical phenomena using light. In multi-photon, two-mode systems, correlations may exist between o…
Local sampling of the Wigner function at telecom wavelength with loss-tolerant detection of photon statistics
G. Harder, Ch. Silberhorn, J. Rehacek +4
We report the experimental point-by-point sampling of the Wigner function for nonclassical states created in an ultrafast pulsed type-II parametric down-conversion source. We use a…
