What's new on Qollab

AWS Braket local simulator

The AWS Braket local simulator is selectable as a backend, alongside qiskit-aer.

Playground simulation ~2.6x faster

qiskit-aer was being compiled with -Oz. Rebuilding it with -O2 made statevector simulation about 2.67x faster, and Aer's AVX2 kernels now run on wasm through Emscripten's SIMD128 emulation.

Python 3.14 in the browser

The in-browser runtime moved from Pyodide 0.29.4 to 314.0.1: Python 3.14, Emscripten 5.0.3, and the pyemscripten_2026 wheel set.

Forum and project discussions

The Qollab forum is live, and every project page has a Community tab backed by it.

• Discourse-backed, with avatars synced from your Qollab profile.
• Author-deleted posts are hidden from search and excluded from comment counts.

Contributor directory and platform stats

/contributor lists everyone building on Qollab. The homepage carries platform stats and a top-creator leaderboard, and both the gallery and profile pages paginate.

qiskit-aer runs in the browser

qiskit-aer is built as a Pyodide/Emscripten wheel and linked against OpenBLAS, so simulation runs locally with no backend round-trip. High-depth circuits now warn before you run them.

IBM simulator backends

IBM simulators are selectable as backends, alongside the Qiskit sampler.

Autosave and coauthors

Project content and code autosave as you work. Projects can list coauthors, so multi-builder work credits everyone.

Video embeds in project write-ups

Project write-ups support YouTube and self-hosted video embeds.

Run without an account

Circuits run without signing in. Sign in when you want to save or publish.

Runs on real quantum hardware

Circuits run on real quantum hardware, not only simulators.
