Landmark experimental paper reporting optical observation of individual T-centre spins in silicon. It moves the platform from ensemble or interface demonstrations into the single-spin regime needed for network-node style quantum hardware.

Key Results

  • Optical observation of individual T-centre spins in silicon
  • Single-spin readout in cavity-coupled silicon nanophotonic devices
  • Strong evidence that T centres can function as silicon-native spin-photon nodes rather than only as ensemble emitters
