中性原子量子计算进展很快，据说到1万这个量级没有原则性困难。

A tweezer array with 6100 highly coherent atomic qubits

Here, we experimentally realize an array of optical tweezers trapping over 6,100 neutral atoms in around 12,000 sites while simultaneously surpassing state-of-the-art performance for several key metrics associated with fundamental limitations of the platform. Specifically, while scaling to such a large number of atoms, we also demonstrate a coherence time of 12.6(1) seconds, a record for hyperfine qubits in an optical tweezer array. Further, we show trapping lifetimes close to 23 minutes in a room-temperature apparatus, enabling record-high imaging survival of 99.98952(1)% in combination with an imaging fidelity of over 99.99%.

毫无意义，这个用来作量子计算需要百万级原子阵列，差了2个量级了。我弟骗经费的和国内学坏了

中性原子量子计算和超导量子计算哪个更靠谱？据说超导量子计算的工作温度已经提升20倍，到1K了

那也就差100倍，别的量子比特类型还差1万倍。

都有困难，超导比特理论上可以扩展到百万，千万比特，中性原子据说很难超过1万，2万这个量级

看来以后每个人背着个稀释制冷机就可以用量子计算机了
