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

Descrizione del progetto

Nuove molecole di carbonio promettono di abilitare operazioni quantistiche a temperatura ambiente

La costruzione del futuro dell’informatica quantistica deve innanzitutto risolvere un grande interrogativo, ovvero come farla funzionare in modo affidabile a temperatura ambiente. Con il sostegno del programma di azioni Marie Skłodowska-Curie, il progetto MG-Spin-Qbits si concentrerà sui grafenoidi molecolari, molecole di carbonio che imitano la struttura a nido d’ape del grafene e sono dotati di notevoli proprietà quantistiche. Utilizzando la chimica umida, i ricercatori progetteranno nuovi grafenoidi molecolari con precisione a livello atomico ed esploreranno il modo in cui sfruttare le loro proprietà magnetiche per lo svolgimento di operazioni quantistiche con l’obiettivo di creare sistemi che funzionino come qubit, ma che mantengano la loro stabilità più a lungo. Liberando il potenziale di questi materiali, la ricerca proposta potrebbe ridefinire il calcolo quantistico scalabile ed efficiente dal punto di vista energetico.

Obiettivo

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.
