摘要: | We report an experimental demonstration of remote preparation of an arbitrary pure qutrit state. A qutrit is encoded in a two-photon (biphoton) polarization state. Prepared states are characterized by quantum state tomography. Experimental imperfection is discussed and evaluated by an experimentally obtained density matrix. The present scheme can develop into generation of an arbitrary two-photon triplet state and accordingly to an essential multiparty quantum communication protocol. Generalization to higher order which enables remote preparation of an arbitrary qudit state and several typical multiphoton entangled states is also shown. |
