Enhanced High-Dimensional Entanglement Generation via Giant-Vortex Slow-Light Polaritons in a Rotating Bose-Einstein Condensate

Abstract

We propose a tabletop experiment to generate high-dimensional orbital angular momentum (OAM)-entangled photon pairs using slow-light polaritons in a rotating Bose-Einstein condensate (BEC) containing a giant quantum vortex. By leveraging electromagnetically induced transparency (EIT) to reduce the effective propagation speed and vortex-induced frame dragging to create an analog rotating spacetime, counter-propagating OAM modes (±ℓ) experience ergosphere-like regions with enhanced coherence. We predict an OAM-dependent excess entanglement lifetime scaling as τexcess ∝ℓ2, arising from disformal couplings in the effective metric. Upon release from the BEC, these entangled polaritons convert to flying photons at c, preserving OAM and entanglement for direct integration into fiber or free-space quantum networks. This provides a novel, robust source of high-dimensional entanglement while offering an analog probe of geometric mechanisms potentially relevant to quantum gravity conjectures such as ER=EPR.

Deterministic All-Optical Quantum Repeater Using Sequential Giant-Vortex Bose-Einstein Condensates

Depio, G.

We propose a deterministic, all-optical quantum repeater architecture based on a linear array of rotating 87Rb Bose-Einstein condensates (BECs), each containing a single giant quantum vortex. High-dimensional orbital angular momentum OAM-entangled photon pairs generated in the first condensate are sequentially handed off as slow-light polaritons to subsequent condensates, where the analog ergosphere refreshes geometric phase protection with excess lifetime τexcess ∝ℓ2. No probabilistic Bell measurements, matter qubits, or cryogenic temperatures are required. Temporal multiplexing yields∼30–100 parallel channels and spatial OAM multiplexing yields 103–104, for a combined >105 logical entangled channels per physical fiber with near-unity fidelity over arbitrary distance. The scheme is directly compatible with existing telecom fiber and offers a practical path toward a global-scale quantum internet.

Generation of polarization-entangled counter-propagating photons with high orbital angular momentum

Elisabeth Wagner, Mikołaj K. Schmidt, Michael J Steel +1 more

Abstract Spin and orbital angular momenta of light are attractive resources to harness for encoding, and manipulating information, with applications in various quantum photonic technologies. However, to fully harness that potential, we require robust sources of high-order angular momentum photons exhibiting nonclassical correlations. Here, we propose a fiber-based source of polarization-entangled photons in high-order orbital angular momentum (OAM) modes. In our setup the pairs of photons are generated in a cylindrical fiber through a four-wave mixing process, which induces polarization, or spin entanglement. The photons are then converted to modes exhibiting large OAM by two helical gratings inscribed in the core of the fiber. We present a complete theoretical framework used to consistently describe this process, and demonstrate a robust control over the joint spectral amplitude of the generated photons.

Vortex entanglement in Bose-Einstein condensates coupled to Laguerre-Gauss beams

Nicola Lo Gullo, Suzanne McEndoo, Thomas Busch +1 more

We study the establishment of vortex entanglement in remote Bose-Einstein condensates (BECs). We consider a two-mode photonic resource entangled in its orbital angular momentum (OAM) degree of freedom and, by exploiting the process of light-to-BEC OAM transfer, demonstrate that such entanglement can be efficiently passed to the matterlike systems. Our proposal thus represents a building block for novel dissipation-free and long-memory communication channels based on OAM. We discuss issues of practical realizability, stressing the feasibility of our scheme, and present an operative technique for the indirect inference of the set vortex entanglement.

Vortex Phase Qubit: Generating Arbitrary, Counterrotating, Coherent Superpositions in Bose-Einstein Condensates via Optical Angular Momentum Beams

Kishore T. Kapale, Jonathan P. Dowling

We propose a scheme for the generation of arbitrary coherent superpositions of vortex states in Bose-Einstein condensates (BEC) using the orbital-angular-momentum states of light. We devise a scheme to generate coherent superpositions of two such counterrotating states of light using well-known experimental techniques. We show that a specially designed Raman scheme allows for transfer of the optical vortex-superposition state onto an initially nonrotating BEC. This creates an arbitrary and coherent superposition of a vortex and antivortex pair in the BEC. The ideas presented here could be extended to generate entangled vortex states, design memories for the orbital-angular-momentum states of light, and perform other quantum information tasks. Applications to inertial sensing are also discussed.

Rotation-enhanced photonic spin Hall effect in a ring Bose–Einstein condensate

Leibo Deng, Muqaddar Abbas, Ghaisud Din +2 more

Abstract We show that rotation can strongly amplify the photonic spin Hall effect in a ring Bose–Einstein condensate. For an incident probe beam carrying orbital angular momentum (OAM), the spin-dependent transverse shift of the reflected light is weak in the non-rotating regime but becomes strongly enhanced under rotation because rotation lifts the degeneracy of the condensate mechanical modes via Bragg scattering. The resulting mode splitting produces large photonic spin Hall shifts at ultra-low optical power, with the enhancement increasing with both the condensate winding number L p and the probe OAM l , while remaining weakly affected by atom–atom interactions. Our findings elucidate a rotation-governed mechanism underlying spin-dependent light transport in hybrid atom–optomechanical systems, thereby highlighting its potential for applications in high-precision rotational sensing.

Angular momentum conversion in the influence of vortex light on electromagnetically induced transparency

Tang Jiangmin, ZHANG Jingtao

In the burgeoning field of light-matter interactions, angular momentum has emerged as a pivotal factor, driving innovative research directions. This study delves into the interaction dynamics between vortex lights and an electromagnetically induced transparency (EIT) medium, with a primary focus on elucidating the underlying mechanism of angular momentum transfer. Through comprehensive theoretical analysis and numerical simulations, it is demonstrated that when the probe field carries orbital angular momentum (OAM), the dispersion and absorption characteristics of the EIT medium undergo periodic modulation. This modulation is intricately determined by the azimuthal phase and topological charge of the beam. Notably, the OAM in the driving field exerts no such influence on the medium's properties. Leveraging vortex phase plates (VPPs) or spatial light modulators (SLMs) to manipulate the tunable OAM enables dynamic control over the EIT effect. This breakthrough not only deepens our understanding of light-matter interactions at the quantum level but also unlocks new avenues for high-dimensional quantum information processing and advanced optical communication technologies.
