有個時空,毛澤東製造了原子彈,有個時空,毛澤東沒有製造原子彈。
有無都在其中,量子計算是也。

第一台商業用量子電腦是在加拿大溫哥華製造。

過去、現在、未來是同時存在,請問“當處出生,當處滅盡”与“凡所有相,皆是虛
妄”該如何与三世同時存在解說?
佛經告訴我們:這些現象的產生,過去、現在、未來是時間上的現象,十方、十法
界是形式上的現象,這些現象全是虛妄的,是從自己妄想、分別、執著產生的,如
果把妄想、分別、執著放下,這個現象就不存在。(信不信由你,這就是薛定愕的
貓裡面說的 entanglement). 放下妄想、分別、執著,這個境界稱作“一真法界”。
一真法界里沒有過去、現在、未來,沒有十方也沒有十法界,這個問題就解決了。

In 1957, Hugh Everett formulated the many-worlds interpretation of
quantum mechanics, which does not single out observation as a special
process. In the many-worlds interpretation, both alive and dead states
of the cat persist after the box is opened, but are decoherent from each
other. In other words, when the box is opened, the observer and the
possibly-dead cat split into an observer looking at a box with a dead
cat, and an observer looking at a box with a live cat. But since the
dead and alive states are decoherent, there is no effective
communication or interaction between them.
When opening the box, the observer becomes entangled with the cat, so
"observer states" corresponding to the cat's being alive and dead are
formed; each observer state is entangled or linked with the cat so that
the "observation of the cat's state" and the "cat's state" correspond
with each other. Quantum decoherence ensures that the different outcomes
have no interaction with each other. The same mechanism of quantum
decoherence is also important for the interpretation in terms of
consistent histories. Only the "dead cat" or "alive cat" can be a part
of a consistent history in this interpretation.
