Job description

About PasqalPASQAL 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.Pasqal’s Quantum Graph Machine Learning (QGML) team is a cutting-edge research & development team focused on advancing quantum computing and graph machine learning (ML). Their work leverages neutral atom QPU to solve complex problems in graph ML. These quantum systems naturally encode classical data like graphs by trapping atoms in a three-dimensional space, allowing us to explore novel approaches where quantum graph kernels and features can outperform classical methods.We are looking for an intern interested in the field of Machine Learning applied to Quantum Computing with a solid background in machine learning and relevant knowledge in many-body physics to reinforce our team.Quantum many-body systems are of great interest for many research areas, including physics, biology and chemistry. Due to the exponential growth of the Hilbert space dimension with system size, their simulation has remained a persistent challenge until today, making it exceedingly difficult to parameterize the wave functions of large systems using exact methods. Many computational techniques are used to overcome these limitations, the most common of which are variational methods, like tensor networks (TN) [1], matrix product states (MPS) [2] and quantum Monte Carlo (MC) [3] to only cite these, where a certain functional form of the quantum state is assumed. More recently, the success of deep neural networks in approximating continuous functions on any compact subset of RN [4] motivated their use for the simulation of quantum systems [5]. To date, these so-called neural quantum states (NQS) have been shown to overcome many problems that are inherent to some conventional methods such as representing volume-law entangled states [6] and can hence (in principle) be used for a broad range of quantum systems. They can also be designed to be particularly well suited for two-dimensional problems. Most prominently, some architectures like convolutional neural networks were specifically designed for two-dimensional data, with relatively good performances on regular grids [7].References[1] Orus R 2014 Annals of Physics 349 117–158 ISSN 0003-4916[2] Schollwock U 2011 Annals of Physics 326 96–192 ISSN 0003-4916 january 2011 Special Issue[3] Becca F and Sorella S 2017 Quantum Monte Carlo Approaches for Correlated Systems (Cambridge UniversityPress)[4] Cybenko G 1989 Mathematics of Control, Signals and Systems 2 303–314[5] Carleo G and Troyer M 2017 Science 355 602–606

The latter offer many suitable properties that allow their simulation at large scales and are also possible to compute on PASQAL’s QPU.The main goals of the project can be summarized in the following: * Implement novel approaches, based on models that efficiently embed the system’s symmetries, enhancing their inductive bias

• Explore the power and the limits of machine learning in representing wave functions that lay in exponentially large Hilbert spaces
• Help in the process of verifying the validity of the obtained results through implementations on PASQAL’s QPU.
