HL 11: Focus Session: Quantum Emitters in 3D Semiconductors

Monday, March 9, 2026, 15:00–18:15, POT/0251

Quantum emitters in 3D semiconductors play a crucial role in many applications. In this focus session, we focus on the latest developments for their use in quantum technologies. In addition to the well-known NV center in diamond, there are a number of other defect centers in various semiconductor systems that hold great potential for quantum sensing, quantum cryptography, and/or quantum information technology. Today’s research focuses on the discovery of new centers, their properties, synthesis, and their microscopic origin. For the latter, ab initio methods are often used, and the material systems span silicon, nitrides, carbides, and other semiconductors with large band gaps.
