Researchers at NIST have demonstrated a breakthrough in quantum communication by making photons from two different quantum sources indistinguishable. The team used a quantum dot and parametric down-conversion crystal to create photons that were nearly identical in spectrum, location, and polarization. This achievement proves in principle that a hybrid quantum network is possible, potentially enabling the creation of quantum computers using different types of quantum components. The research team includes scientists from NIST, the University of Maryland Joint Quantum Institute, and Georgetown University, with partial funding from the NSF Physics Frontier Center at JQI.
