• 👾 DemoDay

  • The Qiskit DemoDays are fortnightly, public meetings with Qiskit developers, where presenters have the opportunity to show off cool things they've been working on and get feedback. More info on past and future DemoDays are in the Wiki
  • Use this Discussion space to:
    • continue conversations about previous DemoDays (recordings are also available in the Wiki),
    • share any ideas you have for upcoming DemoDays
    • volunteer to present in a future DemoDay
    • upvote other DemoDay suggestions that you would like to see

• 📚 Documentation

Labels

Once you've chosen a category and opened a discussion it really helps to add one of the following labels so that others can easily see which area of the SDK you are referring to:

• 🪨 qiskit terra - for discussions relating to qiskit-terra
• 💧 qiskit applications - for discussions relating to qiskit-nature, qiskit-optimization, qiskit-machine-learning or qiskit-finance
• 🔥 qiskit experiments - for discussions relating to qiskit-experiments (ignis)
• 🌬 qiskit aer - discussions relating to qiskit-aer (simulators)

Hi
I would be grateful if someone could help me
i have error traceback on jupyter notebook
that write name 'qft_rotations' is not defined
how can i fix it

[javabster]

hi @hmjafari as explained in the instructions "this space is for productive discussions relating to the development of Qiskit, please do not use this space to ask implementation questions, instead refer to Stack Exchange and the Qiskit slack for this."

If you haven't yet joined the qiskit slack you can use this link: https://qisk.it/join-slack. There are many channels there to ask questions about using Qiskit, I recommend the #qiskit-101 channel for getting started 😄

[hmjafari]

Ok , but this link doesnt work

[javabster]

hi @hmjafari the link was recently refreshed and it has been working for others. Not sure what the issue is for you, what specific error are you getting?

[Mawgaming]

so im working on a flask that uses a combination of python, Qiskit, and npl. it works i dont know how or how to put it together i actually have allot more but i just started learning and dont know much about what im doing but open ai said that i revolutionized the way we look at programming the quantum algorithms I've created and the way i entangle them is unique and are poised to change quantum computing in a way no one ever thought of. Mabey we can help each other

[HiramMartori]

Good morning,
I would like to know if completing the 2021 summer school online now (2023), I can have the certificate.

Thankyou

[javabster]

hi @HiramMartori as explained in the instructions "this space is for productive discussions relating to the development of Qiskit". This space is not intended for questions around events or implementation support, instead please use the Qiskit Slack for these kinds of questions.

If you haven't yet joined the qiskit slack you can use this link: https://qisk.it/join-slack 😄

[HiramMartori]

Ok, thankyou. But this link is not working. How can I access the Slack?

[javabster]

sorry about that @HiramMartori! we recently refreshed the link, it should work now. If not please let us know what error you're receiving

[Jason-Ludmir]

Hi guys,

Thanks for all of your great work. I wanted to point out something that I see might be an inconsistency in the Qiskit documentation.
In the documentation for Qiskit's DAGCircuit, there is a method called "successors" which is defined as:

"Returns iterator of the successors of a node as DAGOpNodes and DAGOutNodes."

This function in practice returns the direct successors to the node in question (i.e. nodes that are a single out-edge away).

However, for the class DAGDependency, there is also a method called "successors" which is defined as:

"Successors id of a given node as sorted list."

This function, while sounding analogous to the one for DAGCircuit, actually returns a sorted list of ALL successors for the given node, no matter how many out-edges away it might be.

The analog can be said for the "predecessors" functions of the two classes.

This is an issue since it is unclear which nodes are either iterated on or returned in a list: All successors/predecessors or just direct ones.

I think an easy/elegant solution would be to add a few words in the documentation of the functions stating specifically how many layers of ancestors/predecessors they return.

I am pretty new to Github and not sure how to add labels, but would label this under documentation =]

Thanks again!

Hi @Jason-Ludmir thanks for feedback :) if you would like to suggest an improvement to the docstring for Dag or Dagdependency please feel free to open an issue here: https://github.com/Qiskit/qiskit-terra/issues

i need some help understanding what i made my flask works vary well in chat gpt but out side of that i need to know what im doing and i dont see the need to keep it to my self the basic flask is in my repo i have a completed versions and am trying to put it together comes with a treasure trove of info in side

Hi, I am just new to qiskit and have been trying to run it in Jupyter Notebook. I have istalled qiskit using pip. But while I am trying to import Quantum Circuit it is showing me the following error:

ImportError: cannot import name 'Self' from 'typing_extensions' (/Users/arindamsutradhar/anaconda3/lib/python3.8/site-packages/typing_extensions.py)

and after this import failure, if I try again to run it, it is showing me the following attribute error. I would really appreciate any help or solution anybody can provide.

Check out https://stackoverflow.com/q/72875257/8146172, it might help.

The Jupyter laboratory works correctly, but the Qistik 1.1 code seems totally erroneous and inconsistent, as if there had been malicious intent. Better to wait 1 more year for these codes to be clear. For the moment I'm going to uninstall Qiskit, which is a shame, because I wanted to compare the measurements to an alternative theory to Shor before I possibly die.

Hi guys, having issues with importing ADAM optimizer and QuantumInstance library from qiskit.
I would be grateful if someone could help me to solve these isssues. Thank you

[1ucian0]

You seems to be calling an unmaintained version of qiskit. Considering installing an old version via pip install qiskit>=0.X (replace X accordantly )

NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

halo my version of qiskit is 1.2.0 and is still not running how to fix it?
