Holographic generation of highly twisted electron beams
Vincenzo Grillo, Gian Carlo Gazzadi, Erfan Mafakheri +3
Free electrons can possess an intrinsic orbital angular momentum, similar to those in an electron cloud, upon free-space propagation. The wavefront corresponding to the electron's…
Divergence of an orbital-angular-momentum-carrying beam upon propagation
Miles J. Padgett, Filippo M. Miatto, Martin Lavery +2
There is recent interest in the use of light beams carrying orbital angular momentum (OAM) for creating multiple channels within free-space optical communication systems. One limit…
Demonstrating Continuous Variable EPR Steering in spite of Finite Experimental Capabilities using Fano Steering Bounds
James Schneeloch, Samuel H. Knarr, Gregory A. Howland +1
We show how one can demonstrate continuous-variable Einstein-Podolsky-Rosen (EPR) steering without needing to characterize entire measurement probability distributions. To do this,…
Induced Coherence, Vacuum Fields, and Complementarity in Biphoton Generation
A. Heuer, R. Menzel, P. W. Milonni
We describe spontaneous parametric down-conversion experiments in which induced coherence across two coupled interferometers results in high-visibility single-photon interference.…
Arbitrary Spin Galilean Oscillator
C. R. Hagen
The so-called Dirac oscillator was proposed as a modification of the free Dirac equation which reproduces many of the properties of the simple harmonic oscillator but accompanied b…
Heisenberg scaling with weak measurement: A quantum state discrimination point of view
Andrew N. Jordan, Jeff Tollaksen, James E. Troupe +2
We examine the results of the paper "Precision metrology using weak measurements", [Zhang, Datta, and Walmsley, arXiv:1310.5302] from a quantum state discrimination point of view.…
