The aim of this annotated notebook is to showcase the widely-used quantum fourier transform algorithm implemented with qiskit. Given a certain input quantum state, this algorithm will generate a quantum circuit that will transform the input state into the Fourier basis.
- Replication of the general QFT algorithm (in example converting 25 in decimal to Fourier basis)
- Make sure it worked using a statevector simulator
- Attach the inverse of the prior algorithm to be able to get definitive results
- Run full circuit on Aer (circuit simulator)
- Compare results to an actual quantum computer

Real quantum computer (former), quantum circuit simulator (latter) 😂 Quantum error correction has a long way to go...
