Just as the title say's im looking for a manga with a complex plot involving quantum physics it can be either horror, sci fi, mystery, supernatural, or psychological. Thanks! edit: (quantum physics (in this instance) would be "supernatural circumstances" but in a scientific explanation sense) just as the person posting below describes.

Lol, that's a pretty hard request. The only thing I could come up with is Manga de Wakaru Riyouko Rikigaku which of course doesn't have a plot unfortunately.
Edit: If you just want a manga with science as an important theme, but with some pseudo-scientific stuff going on, ma favorite is probably Steins;Gate (edit2: Damnedman beated me).

What do you mean by involving quantum physics? Like having in-depth information about quantum mechanics or just utilize it to do something, like time traveling or whatever. Steins;Gate might be what you're looking for but I'm not sure.

It can be either i already eat steins gate it was awesome.

If you're going to ask for something like quantum physics, I think it would be appropriate to give some sort of definition of it so people could recall what you are looking for.

Quantum Physics: the branch of physics based on quantum theory.

• So quantum physics (in this instance) would be "supernatural circumstances" but in a scientific explanation sense.

For example:
The idea of "teleportation" is as follows -
-- An atom size teleportation is possible; human-size teleportation is not.

When a manga explains or produces scientific aspects of a supernatural circumstance, it can be regarded as quantum physics.

In short, quantum physics is MAGIC that is done through scientific means.
So when you read manga about characters being able to control matter, warp through time by running faster than the speed of light, change something as long as it reverts to its original phase, being capable of flying by manipulation of gravitons (gravitation), etc.

Have you tried the manga Psyren?
The manga is complete so you could have fun with that.

Technically Chaos;Head involved more quantum physic than Steins;Gate (but it's not definitely better).

You could also check the tag at anidb if you're interested in anime: http://anidb.net/perl-bin/animedb.pl?wishlist=0&vtype=tag&type.web=1&type.unknown=1&type.tvspecial=1&type.tvseries=1&type.ova=1&type.other=1&type.musicvideo=1&type.movie=1&show=lexicon&relid=388&orderby.name=1.1&orderby.approval=0.2&noalias=1&mylist=0&h=0&do.update=update&cleanurl=1&cat.minweight=100&airing=0
From the bunch, Noein and Kumo no Mukou, Yakusoku no Basho are quite good.

The word "quantum" is not specifically used, but Mahou Shoujo Madoka Magica offers a complex plot backed by scientific explanations, of a sort. I watched the anime version and loved it, but I've read that the manga follows the same plot.

Also, Psyren has a comlex plot involving sci-fi and psi-fi, though I think Madoka is a bit closer to what you're looking for.

Not supernatural but

Yasashii Sekai no Tsukurikata
Denpa Kyoushi

Seem to head that way, but more about the physics itself or something
(but think more of a gokusen/GTO direction)

hmmmm Noein maybe 😕 😕 .... but i dont think it has manga.... or maybe im wrong. dont know 😀

Noein anime is the only thing that comes to my mind when talking about quantum physics.

In Until Death Do Us Part the heroine is precognitive, and the research they do on her abilities and the explanations they give use quantum theories. Also, the organization that ends up protecting her uses a quantum computer made by their genius leader.

I forgot the name of the manga, but it has a lot of physics... cannon gun exxxaxion or something like that?

I found a list you could check out:

1. Icare
2. ES
3. E's Otherwise
4. Stardust Memories
5. Succeed (a oneshot)
6. DNA² (it also has an awesome pervy anime)
7. School Shock
8. The Country of the July 7th Festival
9. A Certain Scientific Railgun and A Certain Magical Index
10. Wolverine Snikt! (I know you said manga, but this OEL is pretty cool)
11. Gantz
12. Route 22
13. Black Paradox
14. Solty Rei - Aka no Shukujo (the anime for this series is very awesome)
15. Verdant Lord
16. Juuki Ningen Jumbor

I am not even sure if all of the ones I listed here are quantum physics related. 🤢
There are others that I know of, but I forgot most of them. Plots, plots, plots...very hard to remember.

I think Sprite

Zetman, may be another great one to check out.
