Area of Science:

• Quantum computing
• Molecular electronics
• Surface science

Background:

• Developing stable molecular quantum bits (qubits) is crucial for advancing quantum technologies.
• Organic molecules offer potential as qubits but often face challenges with surface integration and stability.
• Pyrene-Blatter radicals are known for their stability and unique electronic properties.

Purpose of the Study:

• To investigate the suitability of a pyrene-Blatter radical derivative as a molecular quantum bit.
• To analyze the interface between the molecular quantum bit and a copper surface.
• To assess the stability and coherence of the molecular quantum bit under realistic conditions.

Main Methods:

• Multidisciplinary and multitechnique approach combining surface science and quantum characterization.
• Interface studies of pyrene-Blatter radical derivative on a copper-based surface.
• Evaluation of spin preservation and radical stability in the presence of molecular water and air exposure.

Main Results:

• The pyrene-Blatter radical derivative shows potential as a molecular quantum bit.
• The spin of the interface layer is preserved upon interaction with the copper surface.
• The radical exhibits stability in the presence of molecular water and superior thin-film stability compared to other potential qubits upon air exposure.

Conclusions:

• Pyrene-Blatter radicals are promising candidates for molecular quantum bits due to their inherent stability and preserved spin properties at interfaces.
• Strategies for enhancing molecular systems are discussed to bridge the gap between theoretical potential and practical quantum computing applications.
• This research contributes to the development of robust molecular qubits for future quantum technologies.
