Researchers demonstrate deterministic quantum-state transfer from a 40Ca+ ion to a photon in an optical cavity by controlling the transition probabilities and the frequency difference of two simultaneous Raman fields. They used process tomography to characterize the quantum-state transfer, providing a process fidelity of 92% and a state-transfer efficiency of 16%.
