我们第一次展示了无条件的远程克隆。特别是，我们对称地和无条件地从一个发送器到两个接收器的光的远距克隆相干态，实现了F = 0.58 +/- 0.01的每个克隆的保真度，这超过了经典极限。这是对一种新型的多体纠缠的操纵，这种纠缠的性质既不是纯粹的两体纠缠，也不是纯粹的三方纠缠。
We demonstrate unconditional telecloning for the first time. In particular, we symmetrically and unconditionally teleclone coherent states of light from one sender to two receivers, achieving a fidelity for each clone of F = 0.58 +/- 0.01, which surpasses the classical limit. This is a manipulation of a new type of multipartite entanglement whose nature is neither purely bipartite nor purely tripartite.
