DESCRIPTION:"Strain and Defects in 2D Materials: Quantum Light Emission and
  Nanoscale Sensing"\n\n \n\nPresented by Dr. Huan Zhao\, Distinguished Staf
 f Fellow from the Center for Nanophase Materials Sciences (CNMS) at the Oak
  Ridge National Laboratory\n\n \n\nA scalable\, long-range quantum internet
  will hinge on high-performance photonic qubits for secure communication\, 
 distributed computing\, and advanced sensing. I will show how strain and de
 fect engineering in 2D materials enables deterministic control of spin and 
 excitonic degrees of freedom for quantum light emission and sensing. I will
  briefly survey our near-infrared—especially telecom-band—single-photon emi
 tters realized in monolayers\, multilayers\, and heterostructures\, with em
 ission tuned by strain\, defect species\, and layer number. The second half
  focuses on diamond NV–based single-spin (T₁) relaxometry as a general\, la
 rgely all-optical route to discover\, quantify\, and map spin-active defect
 s in 2D materials with nanoscale resolution\, exemplified by boron vacancie
 s in hBN\; this platform also enables heterogeneous quantum architectures b
 y decoupling sensing and readout into distinct qubits to exploit complement
 ary strengths. All work was conducted at the Center for Nanophase Materials
  Sciences (CNMS)\, a U.S. Department of Energy Office of Science user facil
 ity at Oak Ridge National Laboratory\; I will also briefly introduce CNMS c
 apabilities and how to prepare a user proposal.
