You, or the teleported you? Grey的影片很清楚的說明了這些問題 如果你想要了解更多背景知識 你應該 Grey's video covers these questions really well so if you want more background you should 去看那部影片 但我有一個補充想要說明 go watch that, but I do have one additional piece of information I'd like to point out, 這件事星艦奇航記的創作者們絕對沒有注意到 something the original creators of Star Trek were definitely unaware of because it was 因為它在90年代才被發現 discovered in the 90s. 而這件事 就是量子遙傳 量子遙傳是唯一一種我們現在有辦法達成 And that, is quantum teleportation. 的傳送科技 我不在這裡深入探討細節 Quantum teleportation is the only kind of real teleportation technology we currently 重點是對一群有著特定狀態的粒子 你可以把 have access to, and while I won't go into the details here the point is you can take 完全一樣的量子態傳送給任意遠的另一群粒子 你可能會覺得這是個 some particles in a particular arrangement, and transfer their exact quantum condition "悲哀的瞬間移動" 因為那些粒子並沒有移動 但這不就正是 onto other particles arbitrarily far away. 星艦奇航記的傳送員做的事--不過在大一點的尺度--嗎? You might think of it as “sad teleportation” because the particles don't move, just their 傳送足夠的資訊和能量到另一個地點 來創造跟那些組成"你"的粒子 state – but isn't that essentially what a Star-Trek teleporter does, albeit on a larger 一模一樣的排列方式(或狀態)? scale? 量子遙傳還有另一個重要的性質: 要創造一個完全一樣的量子態 Sending enough information and energy over to the new location to create the exact arrangement, 你一定要摧毀原本的 事實上 你必須摧毀 or state, of particles that corresponds to “you”? 原本的排列方式來獲取所有用來建構 新的 傳送後的 狀態所需的 And quantum teleportation has one pivotal property: it is impossible to create an identical 所有資訊 事實上 相關的量子力學理論被稱為 copy of a quantum state without destroying the original – in fact, you HAVE to destroy "不可複製"原理 the original arrangement in order to extract all the necessary information from it to construct 我們現在還不知道到底大腦是怎麼產生意識的 但如果 the new, teleported, state. 大腦裡的某些電子的量子態對於決定 In fact, the relevant theorem in quantum mechanics is called the “no cloning” theorem. (也對於複製)"你"來說非常關鍵 那麼當要傳送有關粒子的排列方式 Now, we don't yet know exactly how brains work to create consciousness, but if the quantum 的資訊到遠處時 傳送裝置就一定得要遵守量子遙傳的規則 states of some electrons somewhere in the brain are critical to perfectly determining 而無論剩下甚麼東西在原本的位置 它都絕對*不是*你 (and thus copying) “you”, then a teleporter would necessarily have to obey the rules of quantum teleportation when sending the information about the arrangement of particles that are “you” to the new location, and whatever was left behind would definitively *not* be you.
