Those pictures...
So they couldn't project the light that goes on a perpendicular pattern against a surface, and then suddenly they have a "cloak" that does just that and at the same time it also works on different angles of perspective?

I expect the real cloak to be something like the lcd displays, get yourself on a 30° angle or so and watch the hole world bend.

Come on guys. The pics show a "material" that depicts what would be behind it, except for the human being. But if you look carefully and ask "okay, where are those particular photons coming from?" you realise that they are either coming from where a person should be, or they are coming from a place that should be shadowed (and thus a lot darker).

The Onion indeed.

I'll believe this when I see it, and that has to be a video or real life. I do tend to have a hunch feeling that this violates conservation laws regarding photons, but I'm too tired to think it through yet.

And what it comes to some claims made in the video, even I have walked 10 feet away from a soldier and never noticed until he rose up. And that's with a standard uniform.

Modern camo is effective like that, especially dedicated like MARPAT ("universal" camos fare worse in that regard, though Multicam is still good). Ghillies take it up to 11. My friend once nearly sat on a sniper (who was wearing a ghillie suit) before an ASG match. In right environment, if you're not specifically looking for someone dressed in a modern patter, you're not gonna notice him/her.

As for the photos, they looks photoshopped. Most notably, shadows are missing, and I don't think it's metamaterial-based cloaking which would reduce them to a minimum.

You're assuming the photons only pass through one way.

You'd need a "wrap around" effect that allowed photons to enter the material, wrap around it, strike the area on the opposite end (where the photons would have ended jp of nothing was there) and be reflected back without distortion...

Which is still hard to believe.

EDIT: ofc you would need to have the cloak wrapped around you, not just in front or on top, for that to work. Can't imagine no distortion happening, though

Yes, such a cloaking device would cause blatantly obvious distortions, the extent of which is not seen in those photos.  To avoid that the photons would not only need to 'know' exactly how far to travel through the material before exiting again (difficult to believe for person-sized things such as this) but also exactly what angle to exit on, unless the cloak is perfectly symmetric (a sphere).

I'm with Luis and Battuta on this.  Actually, I'm not convinced that the story isn't either bull**** or at least horribly exaggerated.  Show me better evidence.  Yes, I know we have light-bending materials that can act as cloaking devices, but not on such macroscopic scales and variable conditions.  Last time I checked we weren't even able to uniformly bend light of different wavelengths, but maybe I haven't been keeping up well enough.

He doesn't want to jeopardize giving away the secret by allowing actual photos, which could be analyzed. So he's created photo mockups that depict how Quantum Stealth works.

"The real technology functions very similar to what you're looking at in the photos, if not better than what you're looking at in the photos."

So, there's this bridge you may be interested in buying...

[Dragon]

Well, anybody with a photoshop could say that, but on the other hand, it's a valid reasoning. I'm still skeptical, and more info is needed for any serious discussion.

[achtung]

When I read about it on ars or slashdot with some specs and demo shots I'll believe it. Until then, nah.
