Where I can read about protein folding on quantum computer (Qiskit will be ideal variant) with simple examples? Thanks
From a more fault-tolerant perspective, https://arxiv.org/abs/2101.10279 also tackles this problem.
Disclaimer: I am one of the authors :)
Qiskit has already a tutorial on protein folding using Qiskit Nature: Qiskit Nature tutorials - protein folding
Have a look at this recently published paper presenting a protein folding quantum algorithm. This work was done using Qiskit and the algorithm will soon be published as part of the new Qiskit Nature package.
