The emerging field of quantum engineering seeks to design and construct quantum devices for use in technological applications. To do so, one must learn to prepare a physical system in a well defined quantum state, drive it though a specified evolution, and access its final state through measurement. Historically, some of the most successful laboratory platforms with which to explore these challenges have originated in the field of quantum optics. This work reviews some of the recent advances in single- and many atom quantum control at the College of Optical Science, and their integration into a novel atom-light quantum interface.
In this study we report a detailed description of the trapping forces exerted on an arbitrary oriented micron-sized
dielectric spheroid by means of a counterpropagating dual-beam optical trap with a Gaussian transverse field
pattern, using a classical optics approximation. Our analysis includes the calculation of the transverse and axial
trapping efficiencies as function of the normalized beam waist separation distance, normalized spheroid size,
effective index of refraction of the microparticle and ellipticity of the spheroid. The trapping forces produced are
compared with those obtained for spheres.
