It takes about 10 minutes to complete.
The @unitary.foundation annual survey is live!
It’s a great chance to share your experience with quantum software and help shape the bigger picture.
We’re paying close attention, so fill it in, and spread the word!
The Qiskit advocate program got relaunched and applications are open!

For years, folks thought Qiskit was the quantum equivalent of a breadboard, great for teaching, not for real work.
I always disagreed.
Now you don’t have to take my word for it. This Nature Computational Science paper makes it falsifiable: Qiskit is the best production-grade SDK on the market.
Technical release summary for Qiskit SDK v2.0 is out!
🔗 www.ibm.com/quantum/blog...
🇨 Brand-new C API
📈 More performance improvements!
📦 Initial support for boxes and stretches
🚮 Removal of 1.x deprecated functionality (including qiskit.pulse ⚡)
I forgot a super-important link for those transitioning to Qiskit v2.
Here are the migration guides! docs.quantum.ibm.com/migration-gu...
About what's coming:
🇨 The C interface will continue expanding in the 2.x series.
🛣️ See what else is ahead for 2.x in the roadmap qisk.it/roadmap
🪲 As always, if you find any issues, report them on GitHub
github.com/Qiskit/qiski...
Happy quantum hacking! ⚡
About SemVer docs.quantum.ibm.com/open-source/... :
🐍 Qiskit v2 is not backwards compatible with Qiskit v1. Upgrading blindly with `pip install -U qiskit` might break your code.
🦥 Qiskit v1.4 will receive bug fixes until Sept 2025. Use it as a transitional version `pip install -U qiskit>=1.4,<2`
Qɪꜱᴋɪᴛ ꜱᴅᴋ ᴠ2.0 ɪꜱ ʜᴇʀᴇ! 🚀 (Not an April Fools’ joke :) – the release technically happened yesterday in CET)

Qiskit does not do it *that* differently. The last stage of the compilation is scheduling and it's similar to your circuit-to-pulse compiler.
