Precision Synthesis of Magnetic Graphenoids as Room Temperature Two-Qubit Systems

Description du projet

De nouvelles molécules de carbone pour des opérations quantiques à température ambiante

Construire l’avenir de l’informatique quantique exige de résoudre un problème de taille: comment la faire fonctionner de manière fiable à température ambiante. Avec le soutien du programme Actions Marie Skłodowska-Curie, le projet MG-Spin-Qbits sera axé sur les graphénoïdes moléculaires, des molécules de carbone imitant la structure en nid d’abeille du graphène avec des propriétés quantiques remarquables. Grâce à la chimie humide, les chercheurs concevront de nouveaux graphénoïdes moléculaires avec une précision de l’ordre de l’atome et étudieront la manière d’exploiter leurs propriétés magnétiques pour des opérations quantiques. L’objectif est de créer des systèmes qui fonctionnent comme des qubits, mais conservent leur stabilité plus longtemps. En libérant le potentiel de ces matériaux, la recherche proposée pourrait redéfinir l’informatique quantique évolutive et économe en énergie.

Objectif

Quantum computing technologies face a fundamental challenge of scalability, primarily due to the lack of materials capable of performing error-free quantum operations at room temperature. Molecular graphenoids (MGs) have displayed superior quantum properties at room temperature, making them an attractive alternative.

This project will bring novel magnetic graphenoids with atomic precision through scalable solution (wet) chemistry and study them as two-qubit systems at room temperature. This proposal will also uncover the suitability of the spin arrangement (ferromagnetic or antiferromagnetic) in MGs as qubit systems with implications for future developments in the field of molecular quantum materials. In the second part, the project focuses on increasing the spin coherence time, one of the key parameters for quantum operations at room temperature. This will be achieved through structural tuning of MGs to minimize the spin decoherence channels. The overarching goal of the proposed work is to introduce new graphenoids as two-qubit systems, answer a fundamental question, and use the new knowledge generated to tune the respective MGs to achieve a spin coherence time (~100 μs) at room temperature, bringing a major advancement in the field.

The proposed study will be of critical fundamental and practical significance by providing novel graphenoids with potential applications in future quantum technologies. The nature of the proposed project is highly interdisciplinary, involving chemistry, physics, molecular magnetism, and material science. The project is in line with the European objectives of sustainable industrial growth and climate change mitigation.
