# HHL 4x4

Linear system A x = b

This project is a part of the code I produced during my Master’s internship at CERFACS. It implements a super simplified version of the HHL algorithm where the linear system checks all the properties possible that simplify the implementation:

1. Small $4\times 4$ matrix.
2. Eigenvalues of the matrix that are powers of $2$.
3. Right-hand side $b$ easily encodable on a quantum computer.

The implementation uses an old version of qiskit.
