Project description
A new route to quantum computing
Quantum technologies use the laws of physics at the smallest scales to create powerful new computers and sensors. Most current systems use qubits, which can store information in two possible states. However, many quantum systems can naturally hold more information than this. With the support of the Marie Skłodowska-Curie Actions programme, the QutritQIP project will test qutrits, which use three states instead of two, in arrays of carefully controlled atoms. Using qutrits could improve how quantum devices process information, make measurements more accurate, and correct errors more efficiently. By going beyond qubits, the project aims to develop faster, smarter and more scalable quantum technologies for the future.
Objective
Quantum technologies are advancing rapidly, with neutral atoms in optical tweezers emerging as a promising platform for scalable quantum information processing. While many physical systems, including neutral atoms, feature high-dimensional Hilbert spaces, current approaches predominantly rely on two-level, qubit encoding. The QutritQIP project proposes to explore the use of qutrits encoded in three energy levels of strontium-88 neutral atoms to enhance quantum science and technology. Under the supervision of Prof. Immanuel Bloch at the Max Planck Institute of Quantum Optics, I will investigate how qutrits can unlock new regimes in entanglement, metrology, and quantum error correction beyond the current state-of-the-art.
The first objective is the deterministic generation and certification of genuine multi-partite qutrit entanglement, surpassing current bi-partite and post-selected demonstrations and opening a new regime in the study of entanglement. Using qutrit-entangled states, the second objective is to demonstrate quantum-enhanced multi-parameter estimation with the simultaneous estimation of two independent phases in an atomic clock. Finally, I will demonstrate a qutrit-based quantum error correction code, offering practical advantages over qubit-based schemes in terms of resource efficiency.
This work will establish the first scalable use of qutrits in neutral atom arrays and show clear experimental benefits for quantum information science. By moving beyond qubits, this research opens new pathways for more efficient and powerful quantum technologies.
