Fully Homomorphic Encryption (FHE) is a rapidly developing technology that enables computation directly on encrypted data, making it compelling solution for security in cloud-based systems. In addition, modern FHE schemes are believed to be resistant quantum attacks. Although offers unprecedented potential security, current implementations suffer from prohibitively high latency. Finite field ar...

The superconductor Nb3Sn is known to have a superheating field, Hsh, of approximately 400 mT. This critical field represents the ultimate achievable gradient in a superconducting cavity, and is equivalent to an accelerating gradient of 90 MV/m in an ILC single-cell cavity for this value of Hsh. However, the currently best performing Nb3Sn single-cell cavities remain limited to accelerating grad...

The electromagnetic field associated with a uniformly accelerated charge is studied in some detail. The equivalence principle paradox that the co-accelerating observer measures no radiation while a freely falling observer measures the standard radiation of an accelerated charge is resolved by noting that all the radiation goes into the region of space time inaccessible to the co-accelerating ob...

We show that new families of diffraction-free nonparaxial accelerating optical beams can be generated by considering the symmetries of the underlying vectorial Helmholtz equation. Both two-dimensional transverse electric and magnetic accelerating wave fronts are possible, capable of moving along elliptic trajectories. Experimental results corroborate these predictions when these waves are launc...

Previously, imaging and analysis with cathodoluminescence (CL) detectors required using high accelerating voltages. Utilization of lower accelerating voltage for microanalysis has the advantages of reduced beam-specimen interaction volume, and thus better spatial resolution, as well as reduction in electron beam induced damage. This article will highlight recent developments in field emission g...
