Composite Biased Rotations for Precise Raman Control of Spinor Matterwaves
Liyang Qiu, Haidong Yuan, Saijun Wu
Precise control of hyperfine matterwaves via Raman excitations is instrumental to a class of atom-based quantum technology. We investigate the Raman spinor control technique for al…
Spinor matterwave control with nanosecond spin-dependent kicks
Liyang Qiu, Lingjing Ji, Jiangyong Hu +3
Significant aspects of advanced quantum technology today rely on rapid control of atomic matterwaves with hyperfine Raman transitions. Unfortunately, efficient Raman excitations ar…
Imaging moving atoms by holographically reconstructing the dragged slow light
Yuzhuo Wang, Jian Zhao, Xing Huang +6
The propagation of light in moving media is dragged by atomic motion. The light-drag effect can be dramatically enhanced by reducing the group velocity with electro-magnetically in…
Superradiant detection of microscopic optical dipolar interactions
Lingjing Ji, Yizun He, Qingnan Cai +7
The interaction between light and cold atoms is a complex phenomenon potentially featuring many-body resonant dipole interactions. A major obstacle toward exploring these quantum r…
Atomic spin-wave control and spin-dependent kicks with shaped subnanosecond pulses
Yizun He, Lingjing Ji, Yuzhuo Wang +6
The absorption of traveling photons resonant with electric dipole transitions of an atomic gas naturally leads to electric dipole spin wave excitations. For a number of application…
Precise pulse shaping for quantum control of strong optical transitions
Yudi Ma, Xing Huang, Xiaoqing Wang +6
Advances of quantum control technology have led to nearly perfect single-qubit control of nuclear spins and atomic hyperfine ground states. In contrast, quantum control of strong o…
Geometric control of collective spontaneous emission
Yizun He, Lingjing Ji, Yuzhuo Wang +6
Dipole spin-wave states of atomic ensembles with wave vector mismatched from the dispersion relation of light are difficult to access by far-field excitation but may s…
