Tutorial on Variational Quantum EigenSolvers

If you can't explain it simply, you don't understand it well enough - Albert Einstein

This project is an effort to create an easy to understand tutorial on Varaitional quantum eigen solvers. The tutorial used fifferent sources to create a consolidated learning resources with all answers.

The tutorial is a seven part series

• Part1 : Discussion starts from Schrodinger Equation to Significance of Hamiltonian.
• Part2: Dicussion starts from VQA to Steps involved in solving problems using VQE.
• Part3: This includes a code implementation of a defined problem statement
• Part4: This includes explaination about QUBO problems and how NP hard problems like MaxCut can be represented as a QUBO problem. This also includes how we can find Hamiltonian cost function of QUBO problems.
• Part5: This includes neccessary concepts about QAOA implementation and explaination about adiabatic QAOA.
• Part6: This includes the implementation of using QAOA to solve maxcut problem.

If you have any suggestions to improve this repo please submit a pull request. Lets make learning about quantum easy and less intimidating.
