Seoul: A team of Republic of Korean scientists has become the first in the world to successfully measure the quantum distance between two electronic states in solid materials, the science ministry announced Friday. Their groundbreaking research was published in the prominent global journal Science.
According to Lao News Agency, the research team was led by Professor Kim Keun-su of the Department of Physics at Yonsei University and Professor Yang Bohm-jung of the Department of Physics and Astronomy at Seoul National University. The study represents a significant advancement in the field of quantum physics.
“In the publication, we report the first direct measurement of the full quantum metric tensor, or quantum distance, of Bloch electrons in a solid, using black phosphorus as a representative material,” Professor Kim stated during a press briefing. This achievement marks a pivotal step forward in understanding and applying quantum mechanics in practical scenarios.
Accurately measuring quantum distance in so
lids has long been a challenge, despite its potential to serve as a key foundational tool in various quantum technologies, including quantum computing and quantum sensing. The ability to measure these distances precisely is expected to enhance the reliability and efficiency of emerging quantum technologies.
Quantum distance refers to how similar or different the quantum states of two electrons are from each other. It is a fundamental concept that can impact the development and operation of quantum devices. “Just as precise distance measurement is essential for safely constructing buildings, accurately measuring quantum distance is crucial for ensuring the reliable operation of quantum technologies,” Professor Kim explained.
The successful measurement is anticipated to pave the way for further research and development in the field, potentially leading to advancements in a variety of quantum applications. The study highlights the Republic of Korea’s growing influence in the global scientific community and its
commitment to advancing quantum research.
