GAITHERSBURG, Md., March 14, 2011 — An etching method has been revealed that can precisely shape and position quantum dots, making it possible for them to emit single photons. This process could boost prospects for powering new types of devices for quantum communications. The conventional way to build quantum dots is to grow...Read full articleRelated content from Photonics MediaARTICLESDiamond Metalens Could Improve Quantum Device Performance and ScalabilityAt the chemical level, diamonds are no more than carbon atoms aligned in a 3D crystal lattice.
