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…
Weak-value amplification of the fast-light effect in rubidium vapor
Mohammad Mirhosseini, Gerardo Viza, Omar S. Magaña-Loaiza +3
We use weak-value amplification to enhance the polarization-sensitive fast-light effect from induced Raman absorption in hot rubidium vapor. We experimentally demonstrate that proj…
4 X 20 Gbit/s mode division multiplexing over free space using vector modes and a q-plate mode (de)multiplexer
Giovanni Milione, Martin P. J. Lavery, Hao Huang +8
Vector modes are spatial modes that have spatially inhomogeneous states of polarization, such as, radial and azimuthal polarization. They can produce smaller spot sizes and stronge…
Gradient Boundary Histograms for Action Recognition
Feng Shi, Robert Laganiere, Emil Petriu
This paper introduces a high efficient local spatiotemporal descriptor, called gradient boundary histograms (GBH). The proposed GBH descriptor is built on simple spatio-temporal gr…
Quantum homomorphic encryption for circuits of low -gate complexity
Anne Broadbent, Stacey Jeffery
Fully homomorphic encryption is an encryption method with the property that any computation on the plaintext can be performed by a party having access to the ciphertext only. Here,…
The Connes embedding property for quantum group von Neumann algebras
Michael Brannan, Benoit Collins, Roland Vergnioux
For a compact quantum group of Kac type, we study the existence of a Haar trace-preserving embedding of the von Neumann algebra into an ultrapower…
