The publication reveals the real-time capture of quantum information through entanglement, highlighting the transformative potential of this research in quantum technology.

This innovative study enhances the understanding of the exciton formation process and its significance in quantum information technology, demonstrating the real-time capture of quantum information via entanglement.

In collaboration with Professor Noejung Park from UNIST, the team achieved the first successful demonstration of forming and synthesizing exciton and Floquet states in two-dimensional semiconductors, showcasing their potential for real-time quantum information capture.

A research team led by Professor Jaedong Lee from DGIST has unveiled a groundbreaking quantum state and mechanism for manipulating quantum information through the use of exciton and Floquet states.

Two-dimensional semiconductors are particularly advantageous for quantum information devices due to their ability to maintain distinct energy levels for excitons and conduction bands, which helps preserve quantum coherence over longer periods compared to traditional three-dimensional solids.

The weaker screening effects in two-dimensional semiconductors contribute to this longer preservation of quantum coherence, making them a promising material for future quantum technologies.

Overall, this research marks a significant milestone in the field of quantum information technology, with the potential to enhance its practical applications.

The study also sheds light on the previously poorly understood mechanisms of coherence and decoherence of electrons during exciton formation, utilizing theoretical calculations and time-resolved angular-resolved photoelectron spectroscopy.

The research received support from the Korea Research Foundation’s Mid-Career Researcher Support Program, further emphasizing its importance in advancing quantum research.
