Final phase of the QRydDemo project in collaboration with the University of Stuttgart - Development of a compiler for Rydberg atom-based quantum computers
HQS Quantum Simulations (HQS), a quantum startup from Karlsruhe, is supporting the QRydDemo project on behalf of the University of Stuttgart by developing a special compiler. The QRydDemo project is building a quantum computer based on neutral atoms. The compiler developed by HQS is specifically tailored to the unique features of this quantum computer. HQS will continue its support for the project, initiated in 2021 and scheduled to run until January 2025, and will improve the compiler further.
As part of the QRydDemo project, the University of Stuttgart is building a quantum computer that relies on neutral atoms confined within optical tweezer arrays. The use of so-called Rydberg states enables fast switching processes between the atoms, which supports the implementation of fast and high-fidelity gate operations.
In the execution of quantum programs on the QRydDemo platform, the compiler developed by HQS plays a crucial role by optimizing quantum circuits, managing qubit routing, and translating them into native gates. It considers the special requirements and capabilities of the Rydberg-based quantum computer, particularly focusing on shift operations and multi-qubit gates. This approach ensures that the unique capabilities of the resulting QRydDemo hardware are maximally utilized.
The compiler is based on the open-source software qoqo (https://github.com/HQSquantumsimulations/qoqo) developed by HQS to ensure stable and efficient serialization of quantum programs. Specifically, for the QRydDemo Platform, HQS has extended qoqo with additional quantum operations, resulting in an open-source package called qoqo-qryd (https://github.com/HQSquantumsimulations/qoqo_qryd). Furthermore, Qoqo is utilized by the QRydDemo project to establish a Rest API for accessing QrydDemo simulators and future QRydDemo hardware.
The University of Stuttgart expresses high satisfaction with the cooperation with HQS and the quality of qoqo software as the foundational toolkit. "The use of qoqo makes it possible to fully exploit the special hardware capabilities of the QRydDemo platform and to offer stable API access to the platform," as the university states.
