Quick Start: Running Experiments
Task 1: Noiseless QKD
- Go to the QNE Community Application Library by clicking on "Browse all apps" under "Explore" in the main menu
- Find the Quantum Key Distribution app by user hjirovska
- Launch the QKD app
- Click on "Next Step" twice -- we won't touch the hardware parameters for now
- Set "Number of EPR pairs" to 100
- Click on "Next Step" and then "Run"
- Wait for the experiment to finish
- [Optional] View the animation of the experiment by clicking "Start process animation"
- Click on "Next" and then "Load results" to view the results
Check and then share your results:
- What is Alice's raw key?
- Is it indeed the same as Bob's raw key?
- What is the QBER (Quantum Bit Error Rate)?
- Is the QBER good? (Hint: read here to learn more about QBER!)
Task 2: Noisy QKD
- [Optional] If you just ran QKD already, click "Reconfigure" in the top right, otherwise:
- Launch the QKD app
- Click on "Next Step" once, to get into the "Configure the network" section
- Expand the "Delft - The Hague" Network channel and set the Elementary Link Fidelity to 0.500. Note that this is the link that will be used to generate entanglement!
- Click on "Next Step"
- Set "Number of EPR pairs" to 100
- Click on "Next Step" and then "Run"
- Wait for the experiment to finish
- [Optional] View the animation of the experiment by clicking "Start process animation"
- Click on "Next" and then "Load results" to view the results
Check and then share your results:
- What is Alice's raw key?
- Is it the same as Bob's raw key? If no, how many bits are different?
- What is the QBER (Quantum Bit Error Rate)?
- Is the QBER what you expect given Alice's and Bob's raw key? If not, why could this be? (Hint: see here for more info!)
Task 3: State Teleportation
- Launch the State Teleportation app by user hjirovska
- Click on "Next Step" once, to get into the "Configure the network" section
- Expand the "Delft - The Hague" Network channel and set the Elementary Link Fidelity to 0.750. Note that this the link that will be used to generate entanglement!
- Click on "Next Step"
- Set the Qubit state of Sender to the "|+>" state. This corresponds to theta = 0.5 and phi = 0.
- Click on "Next Step" and then "Run"
- Wait for the experiment to finish
- [Optional] View the animation of the experiment by clicking "Start process animation"
- Click on "Next" and then "Load results" to view the results
- [Optional] Re-rerun the same experiment and see if you get different results (like a different fidelity)!
Check and then share your results:
- What is the final state at the Receiver?
- Is it the same as the original state you set for the Sender?
- What is the fidelity between the original state and the teleported state?
Share your results
