MSE802 Quantum Computing

Task 1: Entanglement Demonstrations (LO2)(Circuit)

• Create an entangled bell state using Cirq and run the system on the Quokka device. The Bell state is given as:

Generate qubits and apply necessary gates to generate the above state. Generate the necessary results accordingly.

Task 2: Qiskit circuits (LO1,2)(Circuit)

• Using Qiskit, generate the following circuit:

Measure the output by running it on a quokka device and print the output.

• Write a QASM script for a circuit of your own. Use different qubits and various gates to generate the final circuit. Measure the output by running it on a quokka device and print the output.

Task 3: Investigate a quantum code (LO1,2,4)(Explain what does the code work)

This is a partially developed interactive tic-tac-toe game designed to illustrate the generation of a quantum circuit through gameplay. To engage with this educational tool effectively, you are required to undertake the following tasks:

• Complete the provided code by filling in any missing instructions or comments.
• Once the code is finalized, participate in multiple instances of the game, and perform an in-depth analysis of the generated code.
• In your capacity as a quantum software engineer, elucidate the purpose, functionality of the code, the gameplay dynamics, and the process through which quantum circuits are generated. Compile your findings in a comprehensive Word document.
• Additionally, explore the various quantum gates employed in circuit generation and provide succinct descriptions of each gate's characteristics and functions in a separate section of your document.

• Note: the code file is tic_tac_toe_quantum.ijpynb

Task 4: Machine learning Quantum Analysis (LO1,2,4)(May need to add a couple of lines of code and explain)

You have been provided with a code designed to address a machine learning problem cantered on image classification. The code generates binary images and employs an optimization function to assess sample images, ultimately yielding a metric. This entire process is executed using a specifically tailored circuit.

Your tasks include:

• Analysing the code, with a particular focus on the circuit component and the problem's formulation. Determine the data input into the circuit and identify the portion that serves as the input. Additionally, elucidate the code's functionality, particularly its quantum aspects, excluding the optimization algorithm.
• Executing the code and monitoring the final output at each iteration. Create additional code to plot the iteration number against the output measure. Also, generate a graph depicting the iteration number against the time required for producing the output.
• Modifying the code to run on your local machine, eliminating the need for the quantum computer or circuit. Measure and document the disparities in performance, both in terms of efficiency and effectiveness.
• Compile a comprehensive report summarizing the tasks above.
• For the final task, you are required to submit a modified code (.ijpynb file) and a word document.

• Note: the code file is ML_quantum.ijpynb
