The Integrated Systems Laboratory (Laboratoire des Systèmes Intégrés – LSI) studies design technologies for circuits and systems. The objective is to research the interplay of hardware and software design for traditional (computation on silicon) and non-traditional (nanotechnology and quantum) systems. Topics of research include, but are not limited, to the following areas.

Design technologies for nanosystems, addressed the creation of integrated systems that leverage emerging nanotechnologies. This area includes the modeling of hardware with dedicated languages, the compilation of hardware models into circuits, the relation between hardware and software design and its concurrent design (co-design), the system-level optimization from multiple objectives (e.g., performance, energy consumption, yield). The novel thrust in this area comes form the exploration of the use of new circuits technologies (e.g., superconducting circuits and nano technologies) within system design, presenting unprecedented advantages and challenges.

Giulia Meuli, PhD graduate at the Integrated Systems Laboratory (LSI), received the EDEE best Doctoral Thesis Award in Electrical Engineering, for her thesis “Program Compilation for Large-Scale Quantum Computers”. The recognition is to reward a remarkable PhD thesis work in the field of electrical engineering and quantum computing.

As quantum computers become available resources, an important problem is to automate the translation of quantum algorithms into quantum circuits, which play a role similar to assembly code in traditional computers. Quantum compilation, has been the subject of Giulia Meuli’s thesis, where she also combines compilation with optimization. She implemented her thesis work as part of an open-source project called Caterpillar, which is freely available to researchers and developers. The algorithms and the software presented in her thesis contribute to a widespread effort of the research community to build a complete and efficient software stack to program and control the first practical universal quantum computers.
