  • Quantum light sources, especially single-photon emitters, are key for advancing quantum communications and computing, yet face challenges with low excitation efficiency. Here, the authors enhance GaAs quantum dots using a 3D AlGaAs charge-carrier funnel, significantly boosting emission efficiency and paving the way for efficient electrically driven single-photon emitters in quantum systems.

  • Color centers at the optical fiber low dispersion O-band represent a crucial resource for long-coherence quantum network nodes. This study explores and compares two promising O-band defects in silicon: T centers and *Cu color centers, focusing on their photophysics and spin properties to assess their potential for high-fidelity spin-photon interfaces.
