Increase in repetition delay time maximum

To provide more flexibility for users, we have expanded the allowable repetition delay time range from 20-500 µs to 20-2000 µs on our Heron and Eagle QPUs. The Nighthawk QPU delay time range continues to be 1000-4000 µs as previously announced. Note that if you choose to increase repetition delay (rep_delay), it will have a direct impact on your execution time and capacity consumption, but it might improve the fidelity of certain circuits. The default rep_delay remains unchanged on all QPUs.

You can find more information about repetition delay time, including how to change it, in Qubit initialization.

January 2026

• The latest enhancements to the Compute resources page include the following:

  • Unified QPU view - All QPUs across regions are now displayed in a single table, making it easier to see status and calibrations of the shared fleet across the two regions. (You can still filter the Compute resources table by region using the funnel icon.)

  • Single maintenance schedule - The maintenance schedule is now at the top of the page, even when no events are currently planned. …

• Learn quantum computing in your own language: We're excited to announce that translations are now available across all documentation and learning pages on IBM Quantum Platform! Translations have been the most-requested feature in user feedback, and now, quantum learning and development are more accessible than ever.

  • Translations of tutorials, courses, documentation, and announcements are now available in seven languages: French, German, Italian, Japanese, Korean, Portuguese, and Spanish.

  • Multilingual search: Use the search bar to find what you need in your preferred language.

  • Downloadable resources: Download resources such as guides or tutorials in the language that suits you best.

  • Localized API references: Explore the latest version of the API reference and REST APIs with fully translated documentation (current versions only).

  • Error messages & solutions: Understand issues faster with translated error codes and suggested solutions.

  Find a translation error? Let us know! Submit a translation issue in our GitHub repo.

  Note that there is a processing delay between the publication of new content and its translation, so you might only see the English version of recently released content for a few days while the translation is underway. …
