Article on VQE
The following article explains about problem formulation in Ising model, and also talks about VQE (Variational Quantum Eigensolver).
An interesting analogy from the author. VQE is like tuning a guitar.
- the quantum part would be like assembling the strings of the guitar
- in the classic part, is like to tune each of the strings: play, check the result against expected, tighten or loosen the string, test again
It’s not a perfect analogy, but it helps give you an idea of the concept.
