Outline of Final Research Achievements

We succeeded experiments for quantum entanglement absorption to detect the entanglement between a ground state electron in an NV center and an incoming photon (published in Physical Review Letters), and quantum state transfer from a photon to a ground state electron based on the quantum teleportation scheme (published in Nature Photonics). Transfer fidelity of over 90% was achieved by purifying the transfer events based on post-selection. We also succeeded to prolong the quantum memory time (phase relaxation time) over 100 times by the developed geometric spin echo (published in Nature Communications). The phase relaxation time of world-longest 1.9 ms was achieved by repeating the echo.
