Systems Newsletter January 2024
We are happy to announce the release of several new enabling features and examples for H-Series Users.
User and Group Priority
A new feature has been released to give organization administrators the ability to prioritize their queue by user and group. This feature is helpful when your organization has a mix of low and high priority projects in the queue.
Learn more about this new ability in the Quantinuum Systems Administrator Guide and Quantinuum API Specification for User Management in Quantinuum Training Materials for RIKEN on the RIKEN Box folder.
Partial results retrieval available in pytket
The Quantinuum API supports giving users partial results from unfinished jobs. This can be useful to retrieve results faster, check on the status of large jobs and allow users to quickly diagnose issues in currently running jobs. Support for this feature was recently added to the pytket-quantinuum package.
An example of how to use this feature can be found in the Circuit Submissions via pytket notebook Quantinuum Training Materials for RIKEN on the RIKEN Box folder. More information can be found on the pytket-quantinuum docs page under Partial Results Retrieval.
Variational Experiments on H-Series with pytket
Variational quantum algorithms involve optimizing a trial parametrized wavefunction to estimate the lowest eigenvalue (or expectation value) of a Hamiltonian. In the Quantinuum Training Materials for RIKEN on the RIKEN Box folder, a new example, Quantinuum Variational Experiment with Batching was added showing how to run variational quantum algorithms using pytket and H-Series unique features in English and Japanese. The example walks through an evaluation of the ground-state energy (lowest eigenvalue) of a dihydrogen molecule.
In this example you will learn about:
- Setup of the Hamiltonian of interest in pytket
- Synthesizing symbolic circuits in pytket
- Variational experiments using the batching feature available on H-Series
