“…In free-space a common problem is phase distortions, such as turbulence. Here BG modes do not show complete reconstruction [60], nor does the hybrid combination add value [61], but classical studies have suggested that perhaps such modes may be resilient to beam wander due to turbulence [62]. This is yet to be tested in the quantum regime.…”

Using spatial modes for quantum key distribution (QKD) has become highly topical due to their infinite dimensionality, promising high information capacity per photon. However, spatial distortions reduce the feasible secret key rates and compromise the security of a quantum channel. In an extreme form such a distortion might be a physical obstacle, impeding line-ofsight for free-space channels. Here, by controlling the radial degree of freedom of a photon's spatial mode, we are able to demonstrate hybrid high-dimensional QKD through obstacles with self-reconstructing single photons. We construct high-dimensional mutually unbiased bases using spin-orbit hybrid states that are radially modulated with a non-diffracting Bessel-Gaussian (BG) profile, and show secure transmission through partially obstructed quantum links. Using a prepare-measure protocol we report higher quantum state self-reconstruction and information retention for the non-diffracting BG modes as compared to Laguerre-Gaussian modes, obtaining a quantum bit error rate (QBER) that is up to 3× lower. This work highlights the importance of controlling the radial mode of single photons in quantum information processing and communication as well as the advantages of QKD with hybrid states.

“…hypergeometric-Gaussian, Bessel-Gauss, and Hankel-Bessel beams) instead of LG beams were able to mitigate the effects of disturbances owing to their self-healing and partial coherence features [19][20][21][22][23] . The bit error rates of the transmitted signals carried by high order Bessel beams show smaller values and fluctuations 24 . Apart from the bit error rates, other statistical properties, such as the variance of the fluctuations of the OAM, M 2 -factor, and the displacement error are less affected by these non-diffraction beams.…”

Orbital angular momentum (OAM) mode division provides a promising solution to push past the already exhausted available degrees of freedom available in conventional optical communications. Nevertheless, the practical deployment of OAM within a free-space optical (FSO) communications system is still hampered by a major challenge, namely that OAM-based FSO links are vulnerable to disturbances. Though several techniques, such as using various non-diffraction beams and multiple transmit-receive apertures, are proposed to alleviate the influence of disturbances, these techniques significantly reduce the performance with regard to combating single fading for spatial blockages of the laser beam by obstructions. In this work, we initially demonstrate that a Fabry-Pérot resonant cavity has the ability to implement OAM mode healing, even for a blocking percentage of over 50%. Consequently, the proposed method will expand the use of OAM in the FSO secure communications and quantum encryption fields.

“…All these beams are based on solutions of Helmholtz wave equation in different coordinates systems, respectively. Due to its intrinsic nature, the non-diffraction beams have many applications e.g., micro particles manipulating, optical tweezer [6,7], nonlinear optics [8,9], and communications [10][11][12][13].…”

We first demonstrate the Terahertz quasi-zero-order Mathieu-Gaussian beams with a 0.1-THz continuous wave. To generate these beams, two diffractive elements, a cylindrical lens and an axicon bearing specific phases are fabricated via 3D printing technology. The related numerical simulations are conducted to study intensity distributions and properties on non-diffraction and self-healing of THz quasi-zero-order Mathieu beams in free space. Experimental results are in good agreement with numerical ones. Based on the characteristic of terahertz Mathieu beams, they can be applied to terahertz linear array imaging system and terahertz communication.
