We present a novel scheme for deterministically realizing remote preparation of three-dimensional quantum states in a controlled manner. In this scheme, to link the three legitimate parties, generalized Einstein-Podolsky-Rosen (EPR) states, generalized Greenberger-Horne-Zeilinger (GHZ) states or their combinations are employed to product the shared quantum resources. Then to complete the deterministic controlled remote state preparation (DCRSP) in a three-dimensional system, some suitable sets of mutually orthogonal quantum states are hired as the measuring bases. It is shown that, after performing projective measurements under the proper measuring bases, the remote preparation of two-qutrit equatorial states can be successfully realized under control of a third party with unit successful probability.

二重赤道状态的确定性受控的远程准备

我们提出一种新颖的方案,以可控制的方式确定性地实现三维量子态的远程制备。在此方案中,要链接三个合法方,可以使用广义爱因斯坦-波多尔斯基-罗森(EPR)状态,广义格林伯格-霍恩-泽林格(GHZ)状态或它们的组合来产生共享的量子资源。然后,为了在三维系统中完成确定性受控的远程状态准备(DCRSP),将一些合适的相互正交的量子态集用作测量基础。结果表明,在适当的测量基准下进行投影测量后,可以在第三方控制下以单位成功概率成功实现二夸脱赤道状态的远程准备。
