This research presents a significant refinement in quantum remote control protocols by utilizing hyperentangled states across both polarization and spatial degrees of freedom simultaneously. By enabling the arbitrary manipulation of distant two-qubit states through linear optics and cross-Kerr interactions, this work offers a more resource-efficient pathway for distributed quantum information processing and secure communication networks. The analysis confirms that even under realistic conditions involving finite distinguishability and dissipation, these hybrid operations remain viable for future scalable architectures.
Hyperentangled Photons Remotely Implement Hybrid Quantum Operations
This research details a quantum remote control protocol using two-qubit hyperentangled states, leveraging polarization & spatial degrees of freedom.
Satish Kumar of the Indian Institute of Science Education & Research (IISER) Mohali and Anirban Pathak of the Jaypee Institute of Information Technology have demonstrated a new quantum remote implementation protocol leveraging a unique approach to entanglement. The researchers used a two-qubit hyperentangled state using both the polarization and spatial modes of photons, simultaneously utilizing these two degrees of freedom, a departure from most existing schemes that typically exploit only one degree of freedom at a time. This protocol enables the remote manipulation of…
