The Centre for Quantum Technologies (CQT) in Singapore brings together physicists, computer scientists and engineers to do basic research on quantum physics and to build devices based on quantum phenomena. Experts in this new discipline of quantum technologies are applying their discoveries in computing, communications, and sensing. CQT is hosted by the National University of Singapore. The Centre also has staff at the Agency for Science, Technology and Research, Nanyang Technological University, Singapore, and the Singapore University of Technology and Design. With some 200 staff and students, it offers a friendly and international work environment.

The position will be in the group of Prof. Robert Raußendorf and under the leadership of Martin Plávala. You will be working on using machine learning to construct verifiable witnesses of entanglement and quantum nonlocality. The goal of the project is to construct such witnesses in high-dimensional cases where other methods fail due to a lack of computational resources. The applications will include witnessing entanglement of quantum states, witnessing high-dimensional steering, and witnessing nonlocality in Bell scenarios and quantum networks.

Quantum computing is at the cutting edge of technological innovation, offering the potential to solve complex problems that classical "binary" computers cannot address. Tensor algebra, with its comprehensive mathematical framework, offers crucial tools for modeling and approximating large multidimensional datasets. This thesis seeks to investigate the interplay between tensor networks and quantum computing by proposing original, robust (to decoherence of qubits) quantum algorithms that utilize tensor structures to improve computational efficiency and capabilities. This research requires a multidisciplinary understanding of quantum physics and linear algebra. This thesis topic will benefit from the complementary expertises of Remy Boyer (CRISTAL/SIGMA) for the multilinear algebra aspect and Giuseppe Patera (PhLAM, Quantum Information team) for the quantum physics aspect.

Quantum batteries have garnered significant attention as a novel energy storage paradigm, leveraging quantum phenomena such as coherence, entanglement, and squeezing to outperform classical counterparts. While a substantial body of research has focused on finite-dimensional systems, particularly spin-based and qubit-based models, the potential of bosonic systems, such as harmonic oscillators, remains underexplored. This research aims to bridge this gap, emphasizing the unique advantages offered by continuous-variable setups, including scalability, and compatibility with realistic physical systems, in particular quantum optics and materials.
