| description | Fusing small resource states into a larger, fully connected graph-state is
essential for scalable photonic quantum computing. Theoretical analysis reveals
that this can only be achieved when the success probability of the fusion gate
surpasses a specific percolation threshold of 58.98% by using three-photon GHZ
states as resource states. However, such an implementation of a fusion gate has
never been experimentally realized before. Here, we successfully demonstrate a
boosted fusion gate with a theoretical success probability of 75%, using
deterministically generated auxiliary states. The success probability is
experimentally measured to be 71.0(7)%. We further demonstrate the
effectiveness of the boosted fusion gate by fusing two Bell states with a
fidelity of 67(2)%. Our work paves a crucial path toward scalable linear
optical quantum computing. |
