这是因为它依赖于一个名为约瑟夫森结的超导装置产生量子比特，这种被特别扭曲的电子只有在低温下才稳定。

This is because it relies on a superconducting device called a Josephson junction to produce the qubits, in the form of specially tweaked electrons that are stable only at such low temperatures.

其他技术都需要一堆巨大的机械装置，而约瑟夫森结则可以通过运用利用普通硅芯片的微型装配技术得到。

Other techniques involve huge lumps of machinery, but Josephson junctions can be made using the sort of microfabrication technology employed for normal silicon chips.
