Gaussian boson sampling exploits squeezed states to provide a highly
efficient way to demonstrate quantum computational advantage. We perform
experiments with 50 input single-mode squeezed states with high
indistinguishability and squeezing parameters, which are fed into a 100-mode
ultralow-loss interferometer with full connectivity and random transformation,
and sampled using 100 high-efficiency single-photon detectors. The whole
optical set-up is phase-locked to maintain a high coherence between the
superposition of all photon number states. We observe up to 76 output
photon-clicks, which yield an output state space dimension of $10^{30}$ and a
sampling rate that is $10^{14}$ faster than using the state-of-the-art
simulation strategy and supercomputers. The obtained samples are validated
against various hypotheses including using thermal states, distinguishable
photons, and uniform distribution.

使用高度相似和压缩参数的 50 个输入单模压缩态，通过 100 模超低损耗干涉仪进行随机变换和采样，以及 100 个高效单光子探测器进行采样，实现了一个 $10^{30}$ 维的输出状态空间，采样速率比使用先进模拟策略和超级计算机快了 $10^{14}$，并通过多种假设进行了验证。
