Microsphere kinematics from the polarization of tightly focused nonseparable light
Stefan Berg-Johansen, Martin Neugebauer, Andrea Aiello +3
Recently, it was shown that vector beams can be utilized for fast kinematic sensing via measurements of their global polarization state [Optica 2(10), 864 (2015)]. The method relie…
Experimental generation of amplitude squeezed vector beams
Vanessa Chille, Stefan Berg-Johansen, Marion Semmler +4
We present an experimental method for the generation of amplitude squeezed high-order vector beams. The light is modified twice by a spatial light modulator such that the vector be…
Single-mode squeezing in arbitrary spatial modes
Marion Semmler, Stefan Berg-Johansen, Vanessa Chille +5
As the generation of squeezed states of light has become a standard technique in laboratories, attention is increasingly directed towards adapting the optical parameters of squeeze…
Classically entangled optical beams for high-speed kinematic sensing
Stefan Berg-Johansen, Falk Töppel, Birgit Stiller +6
Tracking the kinematics of fast-moving objects is an important diagnostic tool for science and engineering. Existing optical methods include high-speed CCD/CMOS imaging, streak cam…
Generation of continuous-variable cluster states of cylindrically polarized modes
I. Rigas, C. Gabriel, S. Berg-Johansen +5
Cluster states are an essential component in one-way quantum computation protocols. We present two schemes to generate addressable continuous-variable cluster states from quadratur…
Tools for detecting entanglement between different degrees of freedom in quadrature squeezed cylindrically polarized modes
Christian Gabriel, Andrea Aiello, Stefan Berg-Johansen +2
Quadrature squeezed cylindrically polarized modes contain entanglement not only in the polarization and spatial electric field variables but also between these two degrees of freed…
