Coherent Quantum Optical Control with Subwavelength Resolution

We suggest a new method for quantum optical control with nanoscale resolution. Our method allows for coherent far-field manipulation of individual quantum systems with spatial selectivity that is not limited by the wavelength of radiation and can, in principle, approach a few nanometers. The selectivity is enabled by the nonlinear atomic response, under the conditions of Electromagnetically Induced Transparency, to a control beam with intensity vanishing at a certain location. Practical performance of this technique and its potential applications to quantum information science with cold atoms, ions, and solid-state qubits are discussed.PACS numbers: 32.80. Qk, 42.50.Gy, 03.67.Lx Coherent optical fields provide a powerful tool for coherent manipulation of a wide variety of quantum systems. Examples range from optical pumping, cooling, and quantum control of isolated atoms [1, 2] and ions [3] to manipulation of individual electronic and nuclear spins in solid state [4,5]. However, diffraction sets a fraction of the optical wavelength λ as the fundamental limit to the size of the focal spot of light [6]. This prohibits high-fidelity addressing of individual identical atoms if they are separated by a distance of order λ or less. In this Letter, we propose a method for coherent optical far-field manipulation of quantum systems with resolution that is not limited by the wavelength of radiation and can, in principle, approach a few nanometers.Our method for coherent sub-wavelength manipulation is based on the nonlinear atomic response produced by so-called dark resonances [7]. The main idea can be understood using the three-state model atom shown in Fig.

“…One possibility is to rely on spectroscopic addressability 84 enabled by spatially varying magnetic fields [85][86][87] or Stark shifts [88][89][90] . Another option is to rely on the nonlinearity of the atomic response to light and thus employ techniques such as STED 91 , spin-RESOLFT 92-94 , or dark-state-based techniques [95][96][97] .…”

Controllable quantum spin glasses with magnetic impurities embedded in quantum solids

et al. 2013

Magnetic impurities embedded in inert solids can exhibit long coherence times and interact with one another via their intrinsic anisotropic dipolar interaction. We argue that, as a consequence of these properties, disordered ensembles of magnetic impurities provide an effective platform for realizing a controllable, tunable version of the dipolar quantum spin glass seen in LiHoxY1−xF4.Specifically, we propose and analyze a system composed of dysprosium atoms embedded in solid helium. We describe the phase diagram of the system and discuss the realizability and detectability of the quantum spin glass and antiglass phases.

“…Tripod scheme.-The proposed DDT implementations exploit the tripod scheme [Figs. 1(b) and 1(c)] [6][7][8]10,11,23], in which a four-level atom feels two counterpropagating stationary laser beams and a third orthogonal beam [14,16,17]. The lasers induce transitions between the ground states jji (j ¼ 1, 2, 3) and an excited state j0i with spatially dependent Rabi frequencies 1 …”

Spin Field Effect Transistors with Ultracold Atoms

et al. 2008

We propose a method of constructing cold atom analogs of the spintronic device known as the Datta-Das transistor (DDT), which, despite its seminal conceptual role in spintronics, has never been successfully realized with electrons. We propose two alternative schemes for an atomic DDT, both of which are based on the experimental setup for tripod stimulated Raman adiabatic passage. Both setups involve atomic beams incident on a series of laser fields mimicking the relativistic spin-orbit coupling for electrons that is the operating mechanism of the DDT.
