**Title:** Remove the `canonicalURL` field from demo metadata. **Summary:** This PR removes the `canonicalURL` field from existing demo metadata. The `canonicalURL` field has been superseded by the (autogenerated) `slug` field as of #1228. **Relevant references:** None. **Possible Drawbacks:** None. **Related GitHub Issues:** None. --- **Detailed Changes:** 1. Fixed the `$id` reference in `demo.metadata.schema.0.1.3.json`. 2. Added `demo.metadata.schema.0.1.4.json` which removes the `canonicalURL` field. 3. Updated the example metadata in `demonstrations_metadata.md`. 4. Removed the `canonicalURL` field from existing demo metadata (and adjusted `dateOfLastModification`). 5. Deleted the obsolete `update_metadata.py` script. **Merge Checklist:** * [x] Delete the "Build Website - Text (Test)" GHA workflow which was added for testing purposes. **Verification:** The generated `metadata.json` file in the Glass Onion bucket no longer has any `canonicalURL` fields: <details><summary><tt>metadata.json</tt> Snippet</summary> <p> ```json [ { "authors": [ { "username": "whatsis" } ], "basedOnPapers": [], "categories": [ "Quantum Computing", "How-to" ], "dateOfLastModification": "2024-10-07T00:00:00+00:00", "dateOfPublication": "2024-10-01T00:00:00+00:00", "doi": "", "previewImages": [ { "type": "thumbnail", "uri": "/_static/demo_thumbnails/regular_demo_thumbnails/thumbnail_how_to_use_noise_models.png" }, { "type": "large_thumbnail", "uri": "/_static/demo_thumbnails/large_demo_thumbnails/thumbnail_large_how_to_use_noise_models.png" } ], "referencedByPapers": [], "references": [], "relatedContent": [ { "id": "tutorial_noisy_circuits", "type": "demonstration", "weight": 1 } ], "seoDescription": "Learn how noise models can be built and inserted into a quantum circuit in PennyLane.", "slug": "tutorial_how_to_use_noise_models", "tags": [], "title": "How to use noise models in PennyLane" }, ... ] ``` </p> </details>
…namic circuits" (#1185) **Title:** Constant-depth preparation of matrix product states with dynamic circuits **Summary:** Matrix product states (MPS) form an important class of quantum many-body states. Preparing them is an important subroutine for any algorithm that want to use MPS as an initial state, for example. A recent paper, on which this demo is based, and which it is following closely, generalized a method that reduces the depth of such a preparation circuit to constant scaling, by using auxiliary qubits and dynamic quantum circuits (mid-circuit measurements together with classical feedforward). We here focus on the simplest scenario in the main text of the paper, and implement a simple example in code. The implemented MPS has a parameter controlling the correlation length of the prepared state, which we verify explicitly. **Relevant references:** https://arxiv.org/pdf/2404.16083 https://arxiv.org/pdf/quant-ph/0501096 https://journals.aps.org/prxquantum/pdf/10.1103/PRXQuantum.4.020315 **Possible Drawbacks:** **Related GitHub Issues:** ---- If you are writing a demonstration, please answer these questions to facilitate the marketing process. * GOALS — Why are we working on this now? Mid-circuit measurements recently are/were a focus point in PennyLane. MPS states are used in some quantum chemistry algorithms as initial state. * AUDIENCE — Who is this for? Researchers in quantum algorithms * KEYWORDS — What words should be included in the marketing post? TBD * Which of the following types of documentation is most similar to your file?
