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.
