Here is my final plea to have Dirac Notation added as input to the WQF. This Dirac notation is fundamental to a completer and more versatile WQF. Just trust me on this one, I have been using Dirac Notation in Mathematica using the Quantum AddOn extensively now for more than 5 years and I can attest to its power and versatility, see attached notebook

If you look at the Quantum AddOn all the Dirac notation is there as input and output , it works perfectly . Any book or course on Quantum Computing or Quantum information is introduced in Dirac notation and quantum computer languages , Qiskit and Q# then code this Dirac notation into code .

The steep learning curve is understanding the Dirac notation . eg If you want to understand Quantum Fourier Transforms you are not going to get that from Qikit , or the Quantum Addon or WQF built in functions .

As stated before you need to look at the QFT formulae eg Mike and Ike

"Learning how to input all of those with notation or not requires the same amount of learning curve, and serves different kinds of users. But abstract objects come first, notation sugar later."

The abstract objects are those complicated dirac formulas as in Mike and Ike . If you can code for those then you are mastering QC or QIT, The abstraction is in the notation, master the notation and you master the abstraction.

When I can code like this am I mastering notation or abstraction, I say I am mastering both. So allow these techniques in the WQF

Your claims are simply wrong, indicating lack of proper knowledge/experience with the Wolfram Quantum Framework, or even with the Wolfram Language. One of the essential features of the Wolfram Language is code readability, even for none expert. Notations you like, are, of course, readable for quantum experts only, to say the least. Note those notations are a minor thing in design, and nothing fundamental at all, only a simple formatting in the input/output, as Nik mentioned.

Doug, look at our documentations. I suggest you to explore our paclet more before any judgment. Only to mention a few examples for comparison, try to construct Quantum Switch in other packages or qiskit, or construct a controlled-gate with many control and many target.
