Quantum dots, or artificial atoms, are being pursued as prospective building blocks for quantum information processing architectures. Communication with other, distant quantum dots requires strong coupling between photons and the electronic states of the dots. Mi et al. used double quantum dots defined in silicon and embedded in a superconducting cavity to achieve such coupling. This demonstration in an industry-relevant material bodes well for the large-scale development of semiconductor-based quantum processors.
