As global climate change intensifies, ocean acidification is becoming a ‘relentless killer’ threatening coral reef ecosystems. Recently, a research paper published in the international authoritative journal Research has revealed diverse survival strategies of reef-building corals in response to ocean acidification, providing a new perspective for understanding and protecting this fragile marine ecosystem.

Kyoto, Japan -- As the demand for more secure data transmission increases, conventional communication technologies are facing limitations imposed by classical physics, and are therefore approaching their limits in terms of security. Fortunately, quantum communication may help us overcome these restrictions.

Quantum communication harnesses the quantum nature of light by utilizing single photons as information carriers. This is a fundamentally different approach from conventional communication technologies and has the potential to lead to the development of secure, high-performance communication systems.

These future quantum technologies will require new single-photon emission sources. Recently, extremely thin two-dimensional semiconductors with a thickness of only a few atomic layers have shown great potential due to their excellent electrical and optical properties. Although increasing the efficiency of such single-photon generation is extremely important, the capacity of these materials and its strategy had not been thoroughly explored.
