The classical butterfly effect suggests that the researchers' meddling should have changed it quite drastically.
經典蝴蝶效應表明，研究人員的干預本應該對其有巨大的改變。
In the event, the qubit's original state had been almost entirely recovered. Its state was not quite zero,
結果，這個量子位的原始狀態幾乎完全恢復了。其狀態不是零，
but it was, in quantum-mechanical terms, 98.3% of the way there, a difference that was deemed insignificant.
而是，按照量子力學術語來說，達到了98.3%，這個差別被認為是可以忽略不計的。
"The final output state after the 'forward evolution' is essentially the same as the input state before 'backward evolution'," says Dr Sinitsyn.
‘正向進化’后的最終輸出狀態和‘反向進化’前的輸入狀態一樣，”Sinitsyn博士說。
"It can be viewed as the same input state plus some small background noise."
“它可以被看做是相同的輸入狀態加上一些小的背景雜音?！?/div>
Oddest of all was the fact that the further back in simulated time the damage was done,
最奇怪的是，在模擬時間中，損害造成的時間越早，
the greater the rate of recovery—as if the quantum system was repairing itself with time.
恢復率也越大——就好像量子系統在隨著時間的流逝而自我修復。
The mechanism behind all this is known as "entanglement".
這種機制被稱為“量子糾纏”。
As quantum objects interact, their states become highly correlated—"entangled"—
隨著量子物體相互作用，它們的狀態變得高度相關——“相糾纏”——
in a way that serves to diffuse localised information about the state of one quantum object across the system as a whole.
其方式是將關于量子物體狀態的局部信息擴散到整個系統。
Damage to one part of the system does not destroy information in the same way as it would with a classical system.
對系統某一部分的損壞不會像對經典系統那樣破壞信息。
Instead of losing your work when your laptop crashes,
當你電腦崩潰時，你的工作內容不會丟失，
having a highly entangled system is a bit like having back-ups stashed in every room of the house.
擁有一個高度糾纏的系統就好像是將備份存放在了家里的每個房間中。
Even though the information held in the disturbed qubit is lost, its links with the other qubits in the system can act to restore it.
即使是被干擾的量子位中的信息丟失了，其和系統中其他量子位的聯系可以恢復它。
The upshot is that the butterfly effect seems not to apply to quantum systems.
結果是蝴蝶效應似乎不適用于量子力學。
Besides making life safe for tiny time-travellers, that may have implications for quantum computing, too,
除了保證小小的時間旅行者的安全外，這也可能對量子計算產生影響，
a field into which companies and countries are investing billions of dollars.
各公司和各國都投入了數十億美元在這個領域。
"We think of quantum systems, especially in quantum computing, as very fragile," says Natalia Ares, a physicist at the University of Oxford.
“我們認為量子系統，尤其是量子計算機中的，是非常脆弱的，”牛津大學的物理學家Natalia Ares說到。
"That this result demonstrates that quantum systems can in fact be unexpectedly robust is an encouraging finding,
“該結果證明量子系統其實可以異常堅固，這是一個鼓舞人心的發現，
and bodes well for potential future advances in the field."
也預示著該領域未來的發展潛力?！?/p>
