Quantum teleportation of Gaussian states has a local realistic phase-space description. Extending this to non-Gaussian states, a fidelity of 2/3 is the gold standard for this quantum communication process.

Area of Science:

  • Quantum physics
  • Quantum information science

Background:

  • The standard continuous-variable teleportation protocol has been experimentally demonstrated for Gaussian states.
  • The non-negative Wigner function of these states allows for a local realistic phase-space description of the teleportation process.

Purpose of the Study:

  • To extend the phase-space description to the teleportation of non-Gaussian states using the standard protocol.
  • To establish a benchmark for the successful teleportation of non-Gaussian states.

Main Methods:

  • Utilizing the Wigner function to describe quantum states in phase space.
  • Analyzing the standard continuous-variable teleportation protocol for non-Gaussian states.

Main Results:

  • The phase-space description is successfully extended to non-Gaussian states.

  • Teleportation of non-Gaussian pure states with a fidelity of 2/3 is achievable.

    • Conclusions:

    • A fidelity of 2/3 serves as a "gold standard" for the teleportation of non-Gaussian states.
    • This work provides a framework for understanding and evaluating non-Gaussian state teleportation in phase space.
