Quantum dots might constitute the foundation of quantum communication. They are an efficient interface between matter and light, with photons emitted by the quantum dots transporting information across large distances. However, structures form by default during the manufacture of quantum dots that interfere with communication. Researchers have now successfully eliminated these interferences....

Bright magnetic dipole radiation from two-dimensional lead-halide perovskites  Science Magazine · 2 weeks
Light-matter interactions in semiconductors are uniformly treated within the electric dipole approximation; multipolar interactions are considered "forbidden." We experimentally demonstrate that this approximation inadequately describes light emission in two-dimensional (2D) hybrid organic-inorganic... more
