Superradiant LIDAR
T. Kullick, M. Bojer, J. von Zanthier +1
In recent years, light detection and ranging (LIDAR) has seen a steep rise in the sensitivity of measuring the distances of remote objects. Here, we propose to enhance the sensitiv…
Directional superradiant emission from statistically independent incoherent non-classical and classical sources
S. Oppel, R. Wiegner, G. S. Agarwal +1
Superradiance is one of the outstanding problems in quantum optics since Dicke introduced the concept of enhanced directional spontaneous emission by an ensemble of identical two-l…
Measurement induced focussing of radiation from independent single photon sources
R. Wiegner, S. Oppel, J. von Zanthier +1
We present a technique based on multi-photon detection which leads to a strong focussing of photons scattered by independent single photon emitters. For N single photon sources it…
Quantum interference initiated super- and subradiant emission from entangled atoms
R. Wiegner, J. von Zanthier, G. S. Agarwal
We calculate the radiative characteristics of emission from a system of entangled atoms which can have a relative distance larger than the emission wavelength. We develop a quantum…
Quantum interference and entanglement of photons which do not overlap in time
R. Wiegner, C. Thiel, J. von Zanthier +1
We discuss the possibility of quantum interferences and entanglement of photons which exist at different intervals of time, i.e., one photon being recorded before the other has bee…
Non-locality from N > 2 Independent Single Photon Emitters
C. Thiel, R. Wiegner, J. von Zanthier +1
We demonstrate that intensity correlations of second order in the fluorescence light of N > 2 single- photon emitters may violate locality while the visibility of the signal remain…
