bug fix for the iqp circuit optimization demo. We updated the external package (IQPopt) and this caused an issue because we didn't specify a kwarg in one of the functions. Should be back now. --------- Co-authored-by: Rashid N H M <95639609+rashidnhm@users.noreply.github.com> Co-authored-by: Paul Finlay <50180049+doctorperceptron@users.noreply.github.com> Co-authored-by: doctorperceptron <paul@xanadu.ai>
## Summary: Run `qml sync-v2` from `dev`/`latest` to sync changes in `demonstrations` to `demonstrations_v2`.
Update `Makefile` to be compatible with MacOS. Add small note to README about the recommended way to install Poetry. [sc-94732] --------- Co-authored-by: Rashid N H M <95639609+rashidnhm@users.noreply.github.com>
This PR introduces a few fixes to the V2 demos pipeline to get all demos to build: - Add support for pennylane v0.41.1 and v0.42.0 wrt the `PennyLaneDeprecationWarning` since the containing module has been refactored. This warning is imported by Sphinx before the V2 pipeline installs the dev version of pennylane, so we need a try/catch for importing this module. - Several changes to the dev constraints file, including cirq and constraining PennyLane to install from the RC branch. - A big change to the `qml build` tool. The current tool assumes all constraints can be satisfied together, which just isn't possible once we start installing the `dev` versions of PennyLane, Catalyst, and several plugins. This is addressed here by adding an additional step to the `qml build` tool to install each of these libraries separately at their correct versions. This step mirrors what is currently done in the Makefile. The above have been tested and verified that the entire V2 dev pipeline builds successfully  This PR also syncs recent changes to the demos in `dev` into the `demonstrations_v2` folder, and increases the verbosity of the `qml` build tool so we have better visibility into the behaviour of the pipeline while we're still in testing mode.
Removes unnecessary constraint from the V2 pipelin.
**Context:** This demo only works with `pennylane<=0.40.0` and a specific tensorflow version. **Change:** Mention this in the warning. <img width="866" height="380" alt="image" src="https://github.com/user-attachments/assets/007b5661-6a1b-4b3c-a54e-1abf4957c802" />
**Title:** **Summary:** - The odegen demo is very sensitive to the initial guess. Updating the random seed so that the plot looks nicer. - The classical shadows demo is not compatible with latest jax, and is using an old interface of sklearn **Relevant references:** **Possible Drawbacks:** **Related GitHub Issues:**
**Title:** Adjust output format in `how_to_user_qiskit1_with_pennylane` **Summary:** Corrected two altered output since last modification. **Relevant references:** **Possible Drawbacks:** **Related GitHub Issues:**
**Title:** Fix result for the Demo `how_to_catalyst_lightning_gpu.py` **Summary:** Since JAX v0.5.0, the PRNGKey behaviour has been updated, so using the same PRNGKey with different versions of JAX will impact what outputs jax.random gives. **Relevant references:** **Possible Drawbacks:** **Related GitHub Issues:** [sc-95314] ---- If you are writing a demonstration, please answer these questions to facilitate the marketing process. * GOALS — Why are we working on this now? *Eg.

* Update `ahs_aquila` demo to render `qml.QuantumFunctionError` deprecation warning * Update `qnspsa` demo to stop unravelling parameters to cost function * Update adjoint differentiation demos (`adjoint_diff_benchmarking` and `tutorial_adjoint_diff`) to use autograd instead of JAX * Use log scaling for y-axis of second plot * Update `getting_started_with_hybrid_jobs` demo to render deprecation warning, and use a while loop to block until job metrics are available * Update `quantum_volume` demo with new coupling map and instructions for setting up API key
**Context:** This demo was getting random warnings, ``` /home/runner/work/qml/qml/venv/lib/python3.10/site-packages/cotengra/hyperoptimizers/hyper.py:57: UserWarning: Couldn't find `optuna`, `cmaes`, or `nevergrad` so will use completely random sampling in place of hyper-optimization. warnings.warn( /home/runner/work/qml/qml/venv/lib/python3.10/site-packages/cotengra/hyperoptimizers/hyper.py:76: UserWarning: Couldn't find `optuna`, `cmaes`, or `nevergrad` so will use completely random sampling in place of hyper-optimization. warnings.warn( ``` which seemed to only occur with `cotengra <= 0.7.4`.  **Description of the change:** By upgrading `cotengra` (and `quimb` ... why not?), the warnings disappear. **Benefits:** No more warnings, 
With the latest ecosystem released to PyPI, it's time to update `dev` to use these dependencies. This PR also reverts the change to install pennylane from master instead of the `v0.42.0-rc0` branch. This PR was prepared by first updating PL ecosystem to the latest release, then `poetry lock`. Then the remaining changes came from making the dependency tree happy.⚠️ Important change: `qrisp` and `neural-tangents` were taken out of the `pyproject.toml` dependencies as they create some weird `tensorflow` error, ``` % poetry lock Updating dependencies Resolving dependencies... (6.3s) Package 'tensorflow-macos' is listed as a dependency of itself. ``` This is fine because the only demos that depend on them are non-executable.
