Entanglement and asymmetric steering over two octaves of frequency difference

Author(s): M. K. Olsen

The development of quantum technologies which use quantum states of the light field interacting with other systems creates a demand for entangled states spanning wide frequency ranges. In this work we analyze a parametric scheme of cascaded harmonic generation which promises to deliver bipartite ent...

Isolation of an energetic monocycle optical pulse in the ultraviolet range

Author(s): Yuichiro Kida

An approach is proposed and numerically investigated to isolate an energetic monocycle pulse in the ultraviolet region. Ultraviolet radiation is generated in an attosecond radiation window formed from multicolored, multicycle pulses with mutual phase coherence. Using multiple multicycle pulses with ...

Optical levitation of 10-ng spheres with nano-$g$ acceleration sensitivity

Author(s): Fernando Monteiro, Sumita Ghosh, Adam Getzels Fine, and David C. Moore

We demonstrate optical levitation of SiO2 spheres with masses ranging from 0.1 to 30 ng. In high vacuum, we observe that the measured acceleration sensitivity improves for larger masses and obtain a sensitivity of 0.4×10−6g/Hz for a 12-ng sphere, more than an order of magnitude better than previousl...

Cavity optomechanics in a levitated helium drop

Author(s): L. Childress, M. P. Schmidt, A. D. Kashkanova, C. D. Brown, G. I. Harris, A. Aiello, F. Marquardt, and J. G. E. Harris

We describe a proposal for a type of optomechanical system based on a drop of liquid helium that is magnetically levitated in vacuum. In the proposed device, the drop would serve three roles: its optical whispering-gallery modes would provide the optical cavity, its surface vibrations would constitu...
