About Pasqal

PASQAL designs and develops Quantum Processing Units (QPUs) and associated software tools. 

Our innovative technology enables us to address use cases that are currently beyond the reach of the most powerful supercomputers; these cases can concern industrial application challenges as well as fundamental science needs. 

In addition to the exceptional computing power they provide, QPUs are highly energy efficient and will contribute to a significant reduction in the carbon footprint of the HPC industry.


Job Description

Graphs are used in a vast spectrum of fields. In particular, several combinatorial problems either are or can be defined on graphs, and are of particular relevance for Quantum Computing. Among the quantum computing platforms, neutral atoms are particularly well suited to solving these combinatorial graph problems.

In recent years, the field of quantum computation has been focused on designing algorithms and hardware that can provide an advantage over classical computers. This advantage can take the form of more accurate results, a faster convergence, or even a lower energy consumption. These solutions are developed on very different platforms, using a wide range of technologies. One of the most prominent one is based on Rydberg neutral atoms, where an analog approach can be applied: as opposed to the case of digital quantum computing, the quantum operations are not divided into discrete consecutive steps (gates) but are rather the result of a time-dependent control of the Hamiltonian acting upon the qubits.

During this internship, we’ll study different hard combinatorial/graph problems on several graph classes to benchmark the performance of PASQAL’s solutions against the classical state of the art methods.

The main student’s mission will be:

  • Evaluate and document the performance of state-of-the-art graph solvers on quantum hardware-compatible graphs.
  • Investigate and identify key graph parameters influencing the difficulty for solvers.
  • Develop small-scale versions of challenging graphs for compatibility testing on quantum hardware.
