The discovery of novel materials and functional molecules can help to solve some society's most urgent challenges, ranging from efficient energy harvesting storage uncovering pharmaceutical drug candidates. Traditionally matter engineering -- generally denoted as inverse design was based massively on human intuition high-throughput virtual screening. last few years have seen the emergence significant interest in computer-inspired designs evolutionary or deep learning methods. major challenge...
Spatial modes of light can potentially carry a vast amount information, making them promising candidates for both classical and quantum communication. However, the distribution such over large distances remains difficult. Intermodal coupling complicates their use with common fibers, whereas free-space transmission is thought to be strongly influenced by atmospheric turbulence. Here, we show orbital angular momentum distance 143 km between two Canary Islands, which 50× greater than maximum...
