Correlated vortex generation in a coherent medium

Abstract

Rb atomic system. Utilizing a Ramsey-like configuration with two distinct interaction regions, our approach enables continuous field generation; the first region prepares coherent atomic states, while the second region facilitates the generation of the new field via coherent Raman scattering of the applied laser. We demonstrate that the generated and the applied fields exhibit a positive correlation with extended correlation times. The topological charge transfer and field generation are verified using the tilted lens detection technique, while Ramsey interferometry confirms the presence of phase-sensitive spin coherence in the second interaction region. Our method offers a promising pathway for the continuous creation of correlated fields with prolonged correlation times, having potential applications in quantum information and optical communications.

Generation of vortex-squeezed light in a coherently prepared medium

Fan Meng, HAO ZHU, Xinyao Huang +1 more

In this Letter, we theoretically propose an alternative scheme for generating vortex optical squeezing, based on the Raman scattering process in a coherently prepared medium, distinct from approaches such as parametric down-conversion and four-wave mixing. Our analysis reveals that both the input control field and the generated signal field can exhibit squeezing upon adjusting the relevant system parameters, with the control field exhibiting a greater degree of squeezing under identical conditions. We further demonstrate the existence of optimal squeezing values over a range of tuning parameters, highlighting the flexibility and robustness of the proposed scheme. These findings may offer a new reference for continuous-variable vortex optical squeezing and possess potential applications in domains such as quantum information processing, quantum precision measurement, and quantum sensing.

Generation of correlated and anticorrelated multiple fields via atomic spin coherence

Xihua Yang, Jiteng Sheng, Utsab Khadka +1 more

We report the experimental observation of generation of four and six strongly correlated and anticorrelated laser fields via atomic spin coherence in triple- and quadruple-\ensuremath{\Lambda}-type ${}^{85}$Rb atomic systems. The anticorrelated Stokes and anti-Stokes fields, simultaneously produced through scattering of the applied laser fields off the atomic spin coherence established in advance by the coupling and probe fields, are also highly anticorrelated, respectively, with the corresponding scattering fields. This method can, in principle, be used to create correlated and anticorrelated narrowband multiple fields of any desired order with long correlation times. It paves the way to further study of the generation of multifield quantum correlations and anticorrelations of arbitrarily high order.

Continuous-variable entanglement with orbital angular momentum multiplexing in coherently prepared media

Fan Meng, Hao Zhu, Xinyao Huang +1 more

Quantum entanglement constitutes a pivotal resource, serving as a fundamental cornerstone within the field of quantum information science. In recent years, the study of vortex light entanglement has garnered widespread attention due to its unique structure and inherent advantages; however, the majority of these investigations are primarily focused on discrete variable systems. In this paper, we present a theoretical framework for generating vortex optical entanglement in coherently prepared media, employing continuous-variable analysis and leveraging Raman scattering as an alternative to the conventional spontaneous parametric down-conversion method. The entanglement arises from the quantum correlation between the two light fields, induced by atomic coherence. Using numerical simulations, we thoroughly explore the impact of various tunable system parameters on the degree of entanglement, ultimately identifying the optimal conditions for maximal entanglement. Our findings offer a reference framework for vortex light entanglement, with potential implications across quantum teleportation, quantum key distribution, quantum computing, high-dimensional quantum information, and other related fields.

Coherent mid-infrared vortex generation at room temperature for manipulation of microparticles

Nawaz Sarif Mallick

We investigate the generation of mid-infrared (mid-IR) vortex beams carrying orbital angular momentum (OAM) through nonlinear processes in an inhomogeneously broadened 85 Rb atomic ensemble. By employing a four-level atomic system featuring two strong control fields and a weak probe field, we generate a non-degenerate four-wave mixing signal at a wavelength of 5.23 µm. Applying the density-matrix formalism, we derive an analytical expression for the nonlinear atomic coherence which facilitates the transfer of vortex characteristics such as topological charge and intensity and phase profiles from the probe field to the mid-IR signal. Numerical solutions of Maxwell’s wave equation confirm the generation of mid-IR vortex beams with adjustable topological charges and beam widths at different spatial positions. This technique offers significant potential for applications in mid-IR communication, providing additional bandwidth and improved data transmission rates, as well as in fields such as microfluidics, biophysics, and nanotechnology, where OAM-carrying beams can manipulate microparticles with precision.

Ramsey interferometry with an atom laser

D. Döring, J. E. Debs, Nicholas P. Robins +3 more

We present results on a free-space atom interferometer operating on the first order magnetically insensitive |F = 1,mF = 0) --> |F = 2,mF = 0) ground state transition of Bose-condensed (87)Rb atoms. A pulsed atom laser is output-coupled from a Bose-Einstein condensate and propagates through a sequence of two internal state beam splitters, realized via coherent Raman transitions between the two interfering states. We observe Ramsey fringes with a visibility close to 100% and determine the current and the potentially achievable interferometric phase sensitivity. This system is well suited to testing recent proposals for generating and detecting squeezed atomic states.
