High-speed integrated ultra-violet electro-optic modulators

Descrizione del progetto

Luce ultravioletta per un’informatica quantistica accurata e scalabile

L’informatica quantistica promette di rivoluzionare la tecnologia, ma per svilupparne appieno il potenziale sono necessarie soluzioni innovative alle attuali sfide tecniche. Con il sostegno del programma di azioni Marie Skłodowska-Curie, il progetto HEIVOM si concentrerà su come controllare i qubit utilizzando la luce ultravioletta. Per farlo, i ricercatori creeranno dispositivi minuscoli e ad alta velocità chiamati modulatori elettro-ottici in grado di gestire la luce ultravioletta. Per costruire tali modulatori verrà utilizzato un materiale speciale, il tantalato di litio su isolante, insieme a tecniche innovative come la stampa 3D per un migliore controllo della luce. Affrontando queste sfide, HEIVOM mira a rendere l’informatica quantistica più affidabile e scalabile, avvicinandoci al suo incredibile potenziale in settori quali l’intelligenza artificiale e la sanità.

Obiettivo

Quantum computing has the potential to revolutionize various fields including life science, communication, and artificial intelligence. Strontium-based neutral atoms are emerging as a promising approach to quantum computing due to their long coherence time and scalability potential. However, a key challenge in these systems is the optimal and scalable control of qubit gates at UV wavelengths, an area where there remains a significant gap.
The objective of this project is to develop high-speed integrated electro-optic modulators (EOMs) at UV wavelengths for optimal, high-fidelity control of neutral-atom-based qubit gates. To date, attempts to realize such systems have faced obstacles due to challenges of suitable materials, nanofabrication techniques, and integrated UV optoelectronic measurement strategies.
To address these, I propose using the novel thin-film lithium tantalate on insulator (LTOI) material platform and exploring its nanofabrication methodologies. The first aim is to develop design guidelines and nanofabrication processes for LTOI UV photonic integrated circuits (PICs). The second aim is to explore a high-efficiency UV coupling method based on 3D nanoprinting. The third aim is to establish an optoelectronic measurement setup and realize high-speed UV EOMs with a high extinction ratio. To achieve these goals, I will collaborate with leading experts and interdisciplinary researchers in my host group at UHEI, and leverage my strong background in photonics, nanofabrication, and electrical engineering. The integrated EOMs developed through this project will fill the gap in UV PICs and bring us closer to the full potential of quantum computing.
This fellowship will enhance my scientific and transferable skills, foster pioneering work in UV optoelectronics and enable further collaborations. It will expand my international network and strengthen my leadership and management skills, which are crucial for my growth into a senior researcher.
