        In “The Curious Case of Benjamin Button,” a story by F. Scott Fitzgerald and then a movie starring Brad Pitt, a man ages backward: He is born an old man, regresses over the years and dies an infant.

        《本杰明·巴頓奇事》是菲茨杰拉德所創作的小說,隨后被翻拍成布拉德·皮特主演的電影,在這個故事里有個男人的年齡是倒退的:他生來是個老人,隨后一直逆生長直至以嬰兒狀態死去。

        This is not typically seen in regular life. The question is, why not?

        這在日常生活中并不常見,但問題是,為什么不呢?

        In what amounts to a technological triumph for the aspiring Benjamin Buttons of the virtual world, a team of quantum physicists reported earlier this year that they had succeeded in creating a computer algorithm that acts like the Fountain of Youth.

        今年早些時候,一組量子物理學家報告稱,他們成功地創造出了一種電腦算法,其功能就像不老泉一樣。這對希望實現虛擬世界中的本杰明•巴頓的人來說,在技術上是一場勝利。

        Using an IBM quantum computer, they managed to undo the aging of a single, simulated elementary particle by one millionth of a second. But it was a Pyrrhic victory at best, requiring manipulations so unlikely to occur naturally that it only reinforced the notion that we are helplessly trapped in the flow of time.

        利用IBM量子計算機,他們成功地將單個模擬的基本粒子的老化過程倒退了百萬分之一秒。但這充其量是一場代價巨大的勝利,需要的操作基本不可能自然發生,這只會強化這樣一種觀念:我們被牢牢困在時間的洪流中,沒救。

        Most of us already sense that the atoms of a scrambled egg can’t be unscrambled back inside a pristine shell. Now it seems that, under general conditions, even a single particle probably can’t go backward without help and careful tinkering.

        我們大多數人已經意識到,炒蛋的原子無法被重新放入一個原始的殼內。現在看來,在一般情況下,如果沒有幫助和仔細的修補,即使是單個粒子也可能無法倒退。

        “We demonstrate that time-reversing even ONE quantum particle is an unsurmountable task for nature alone,” Valerii M. Vinokur, of Argonne National Laboratory, said in an email message; he is one of the five aspiring time lords led by Gordey B. Lesovik of the Moscow Institute of Physics and Technology.

        阿貢國家實驗室的Valerii M. Vinokur在一封電子郵件中說,“我們證明,即使是對一個量子粒子來說,自然狀態下,時間逆轉也是一項無法克服的任務。”他是由莫斯科物理與技術學院的Gordey B. Lesovik所領導的五個有抱負的時間領主之一。

        “The system comprising two particles is even more irreversible, let alone the eggs — comprising billions of particles — we break to prepare an omelet.”

        “由兩個粒子組成的系統更不可逆,更不用說我們做蛋餅時打碎的雞蛋里那數十億個粒子了。”
