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

Descripción del proyecto

Nuevas moléculas de carbono auguran operaciones cuánticas a temperatura ambiente

El desarrollo de la computación cuántica del futuro requiere resolver primero una limitación importante: cómo hacer que funcione de forma fiable a temperatura ambiente. En este contexto, el proyecto MG-Spin-Qbits, financiado por las acciones Marie Skłodowska-Curie, se centrará en los grafenoides moleculares, moléculas de carbono que imitan la estructura en panal del grafeno y que exhiben unas propiedades cuánticas destacadas. Los investigadores emplearán la química húmeda para diseñar nuevos grafenoides moleculares con precisión atómica y, a continuación, estudiar cómo aprovechar sus propiedades magnéticas para ejecutar operaciones cuánticas. El objetivo es crear sistemas que funcionen como cúbits, pero que mantengan su estabilidad durante más tiempo. Al aprovechar el potencial de estos materiales, la investigación propuesta podría redefinir la computación cuántica escalable y eficiente en términos energéticos.

Objetivo

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.
