Characterization of spatial Schmidt modes in high-gain SU(1,1) interferometers
D. Scharwald, P. R. Sharapova
Multimode quantum light has promising applications in many areas of physics, such as quantum communications and quantum computing. However, its multimode nature also makes it chall…
Hybrid SU(1,1) interferometry in optomechanics
Chao Meng, Emil Zeuthen, Polina R. Sharapova
In non-degenerate SU(1,1) interferometers, beam splitters are replaced by two-mode squeezers, enabling sub-shot-noise sensitivity without input squeezing and robustness to detectio…
Generation of polarization-entangled counter-propagating photons with high orbital angular momentum
Elisabeth Wagner, Mikolaj K. Schmidt, Michael J. Steel +1
Spin and orbital angular momenta of light are attractive resources to harness for encoding, and manipulating information, with applications in various quantum photonic technologies…
Schmidt modes carrying orbital angular momentum generated by cascaded systems pumped with Laguerre-Gaussian beams
D. Scharwald, L. Gehse, P. R. Sharapova
Orbital Angular Momentum (OAM) modes are an important resource used in various branches of quantum science and technology due to their unique helical structure and countably infini…
