These are the solutions I submitted for the IBM Quantum Challenge - Fall 2020
The original challenge repository is at /qiskit-community/IBMQuantumChallenge2020
Site: IBM Quantum Experience
Date: November 2020
Here's a screenshot of my challenge portal dashboard.
I got the 46th best score in the final challenge.
And here's my advanced badge, for completing all the exercises.
The solutions are coded in exXX_en.ipynb in the exercises folder. Each also has .html copies for easier reference.
The .ipynb are all self-contained, with explanations, problem statements and the exercise portion at the end.
There are also completed mini-puzzles in quizzes, and the hints you get after completing them in hints.
ex1a - Full Adder
ex1b - Grover's Algorithm | Basics
ex2a - Grover's Algorithm | Implementation
ex2b - Grover's Algorithm | QRAM & Larger Search Spaces
final - Grover's Algorithm | Choosing Oracles
