Note

With a focus on Heralded Quantum Purification (HEP) protocols

We assume that the repeater network operates on optical fibre communication links, though free-space satellite to ground links also employ the same concepts of a quantum repeater.

Objectives

Main Objective

To design and implement a modern quantum repeater infrastructure for future quantum communication technologies and teleportation application.

Specific Objectives

  • To design and implement a complete quantum circuit of a quantum repeater whose executions emulate its expected workings and behaviour in a real world quantum network.
    • Bell states preparation component
    • Bell states measurement (BSM) component
    • Entanglement swapping component
      • Quantum teleportation component
    • Entanglement purification component
      • Bennett's protocol
      • Deutsch's protocol
  • Explore various purification strategies to identify the optimum strategy.
    • After generation/production of Bell Pairs?
    • After every swap?
    • After N swaps?
    • At the ends of the nodes?
    • A suitable combination of various steps?
  • Perform optimizations on the purification circuits and studying the effects of various purification protocols on the overall purification optimization scheme.
    • Employ different purification protocols on the optimization scheme being utilized.
