### Describe the problem I can't find a guide to citing the textbook or a doi, as there are for other parts of Qiskit. For example, the Authors and Citation...

### What should the reader gain from this new content? By the No cloning theorem one cannot clone an arbitrary quantum state rather imperfect quantum copying exists. By training a...

New Content Suggestion

When I run the notebook there are two main things that do not work as intended: 1. manila does not support qiskit pulse, only Armonk works with it. 2. instead...

### What should the reader gain from this new content? By reading this section the reader should be able to simulate the one-dimensional Schrodinger equation for any position-dependent potential on...

New Content Suggestion

### Describe the bug The second code exercise in "Your first quantum circuit" does not run, because the "QuantumCircuit" module is not being imported. Adding `from qiskit import QuantumCircuit` to...
