Overview

Randomized trial demonstrates high-dimensional entangled state analysis in four-photon systems, indicating promise for quantum information processing.

Key Points

  • The aim is to present a deterministic scheme for analyzing high-dimensional entangled states and its applications in quantum teleportation.
  • Developed a four-dimensional two-qudit Bell entangled state analysis.
  • Utilized a three-photon Toffoli gate and quantum nondemolition detectors.
  • Distinguished 16 orthogonal four-dimensional Bell states via coherent beam phase shifts.
  • Achieved complete distinguishability of four-dimensional Bell states using the proposed methods.
  • Demonstrated applications in both uncontrolled and controlled quantum teleportation protocols.
  • Obtained high fidelity and efficiency, enhancing the scope of high-dimensional quantum information processing.
