Systems Newsletter December 2024

We are happy to announce the release of:

• our new product documentation site;
• Quantinuum Nexus;
• two new enabling tools for Quantinuum Systems users;
• upcoming release of H2-2.

New Documentation Site

Documentation for all Quantinuum products can now be found in one easy to browse and publicly available location. Start exploring and learning about all Quantinuum products here.

Quantinuum Nexus

We have officially launched Nexus, our all-in-one quantum computing platform designed for managing, storing, and executing quantum workflows. Nexus will replace the original user portal which will be sunset at the end of Q1 2025. Documentation for Nexus can be found on the documentation site. Learn about Nexus beta users' experiences and results in our product-updates post.

The QEC Decoder Toolkit

Quantinuum offers a real-time hybrid compute capability for Quantum Error Correction (QEC) workflows. This capability executes Web Assembly (Wasm) in the hardware stack and enables use of libraries (e.g. linear algebra and graph algorithms) and complex data structures (e.g. vectors and graphs) during real-time execution of a quantum circuit. The primary purpose of this environment is to provide a real-time classical compute environment for QEC decoding. A knowledge article on this capability can be found here: QEC Decoder Toolkit

Circuit Stitching

Circuit stitching is a workflow to "stitch" multiple jobs into 1 job using the Mid-circuit Measurement & Reset (MCMR) hardware feature. The first benefit is to minimize Hardware Quantum Credits (HQCs) consumption for experiments consisting of multiple jobs. The second benefit is the reduction of job runtime because many jobs are stitched into one job submission. This is very effective for classical shadow use cases where each shot is a new job.

H2-2 Release

Coming Soon: the H2-2 quantum computer will be available to customers with an H2 subscription. Those customers can find the details in the linked PCN. Please reach out if you have questions on any of the above.
