**Describe the issue** in section 2.2 [here](https://qiskit.org/textbook/ch-gates/multiple-qubits-entangled-states.html) there is an image that is partly behind the right hand menu. It is when the text says: `The operation looks like this:`...
**Describe the problem** The first notebook in chapter 6. Investigating Quantum Hardware Using Microwave Pulses is about the calibration of qubits with Qiskit Pulse [(here)](https://qiskit.org/textbook/ch-quantum-hardware/calibrating-qubits-pulse.html). This chapter is very rich...
#Describe the issue 4. Quantum Algorithms for Applications, 4.1.3 Solving combinatorial optimization problems using QAOA, 5.3 Quantum circuit The decomposition of Uk,l(γ) and Xk(β) is given as Uk,l(γ)=Cu1(−2γ)k,lu1(γ)ku1(γ) Xk(β)=Rx(2β)k which...
**Describe the issue** This passage is really hard to read. First the perturbation is calculated in the first equation The sentence about S does not to do anything with it,...
**Describe the bug** When using the search function, the results contain pages from all translations, and not just the language the user is currently viewing in. **To Reproduce** 1. Type...
**What should the reader gain from this new content?** I want to suggest a chapter on quantum information. After reading the chapter the student will understand about other representations of...
**Is your feature request related to a problem? Please describe.** Quantum Computing Labs chapter of the texbook has no way to verify if the queries submitted are right. **Describe the...
**Describe the issue** Though we might want to refer to "statevector" as direct reference to how we type it in python, "statevector" (one word) has been adopted in current language...
### **What should the reader gain from this new content?** This is a proposal for a potential new chapter. The main goal of the chapter is to introduce ZX-calculus, a...
**Describe the problem** I think some things can be added in this section for better clarity for first time readers. **Describe the expected solution** In [5.5.2 Mixed States](https://qiskit.org/textbook/ch-quantum-hardware/density-matrix.html#2.-Mixed-States-), The content...
