mrtkp9993/QuantumComputingExamples ? reverse-engineered prompt

Build me a small Python project that shows off a bunch of classic quantum computing examples using Qiskit.

I want separate scripts for the main algorithms, like Deutsch, Deutsch Jozsa, Bernstein Vazirani, Simon, QFT, Grover, Shor, superdense coding, quantum teleportation, phase estimation, and the swap test. Each example should be easy to run on its own and should print or show the result clearly so someone can follow what is happening. If it makes sense, include simple circuit drawings or saved diagram images like the examples in the README.

Keep the code beginner friendly and focused on teaching the idea behind each algorithm, not on building a full app. Please make sure the scripts work with current Qiskit docs, and update anything outdated if needed. Add a short README style explanation for each example so it is clear what problem it solves and what the output means.
