Summary
We present a method for remotely preparing three-dimensional optical vortex lines using high-dimensional orbital angular momentum entanglement. This technique allows for the creation of complex 3D vortex structures by adjusting the pump beam waist.
Area of Science:
- Quantum optics

- Orbital angular momentum (OAM) is a fundamental property of light.
- High-dimensional entanglement is crucial for advanced quantum information processing.
Purpose of the Study:
- To propose a feasible scheme for remotely preparing three-dimensional (3D) optical vortex lines.
- To explore the generation of complex 3D vortex morphologies.
Main Methods:
- Utilizing high-dimensional orbital angular momentum (OAM) entanglement described by Laguerre-Gaussian modes.
- Theoretically demonstrating remote state preparation by adjusting the pump beam waist.
Main Results:
- Successfully demonstrated remote preparation of target photons in 3D vortex states.
- Observed diverse morphologies including twisted strands, separated loops, and vortex knots.
