Abstract Atom optics demonstrates optical phenomena with coherent matter waves, providing a foundational connection between light and matter. Significant advances in have followed the realization of structured fields hosting complex singularities topologically non-trivial characteristics. However, analogous studies are still their infancy field atom optics. Here, we investigate experimentally create knotted quantum wavefunctions spinor Bose–Einstein condensates which display topologies. In...
A coherent two-photon optical Raman interaction in a pseudo-spin-1/2 Bose–Einstein condensate (BEC) serves as q-plate for atoms, converting spin to orbital angular momentum. This has singular pattern its polarization distribution analogy the birefringent q-plates used optics. The vortex winding direction and magnitude well final state of BEC depend on initial topology beams. Drawing mathematical geometric foundations optics, we derive equivalent Jones matrix this use it create characterize...
AbstractWe explore the geometric interpretation of a diabatic, two-photon Raman process as rotation on Bloch sphere for pseudo-spin-1/2 system. The spin state spin-1/2 quantum system can be described by point surface sphere, and its evolution during pulse is trajectory determined properties optical beams: area, relative intensities phases frequencies. We experimentally demonstrate key features this model with 87Rb spinor Bose–Einstein condensate, which allows us to examine spatially...
We propose a practical protocol to generate and observe non-Abelian geometric phase using periodically driven Raman process in the hyperfne ground state manifold of atoms dilute ultracold gas. Our analysis is based upon recent developments application Floquet theory quantum systems. The simulation results show gauge transformation non-commuting property SU(2) operators. Based on these results, we possible experimental implementation with an Bose
Quantum computers must achieve large-scale, fault-tolerant operation to deliver on their promise of transformational processing power [1-4]. This will require thousands or millions high-fidelity quantum gates and similar numbers qubits [5]. Demonstrations using neutral-atom trapped manipulated by lasers have shown that this modality can provide high two-qubit gate (CZ) fidelities scalable [6-10]. However, the in these demonstrations are driven do not resolve individual qubits, with universal...
We present methods to create waveplates and phase plates for pseudo-spin-1/2 atomic systems via two-photon Raman interactions. The interactions are geometrically represented as rotations on the Bloch sphere.
The formal correspondences between pseudo-spin-1/2 systems in optics and atomic physics have provided fertile ground for exploring polarization atom optics. Previous experimental results demonstrated polarimetry techniques two-level wave functions explored wave-field singularities the multicomponent function of a spinor Bose-Einstein condensate using visualization developed [J. T. Schultz, A. Hansen, N. P. Bigelow, Opt. Lett. 39, 4271 (2014); J. Optica 3, 355 (2016)]. Here we further this...
