A material that makes a person vanish mid-frame, using nothing but plastic and light.

CNET got its hands on physical prototypes of Quantum Stealth, the so-called “invisibility cloak” material built by Canadian camouflage company Hyperstealth Biotechnology Corp. The sheets do something that sounds like science fiction: hold one up in front of a person or an object, and that person or object disappears from view, with the background stretching seamlessly across the gap. There’s no power source, no screen, no computer processing — just plastic and the physics of light.

• Hyperstealth, led by CEO and inventor Guy Cramer, filed four patent applications covering Quantum Stealth in October 2019 after years of keeping the material under wraps.
• The effect comes from classical optics, not “quantum” anything — sheets of lenticular lenses, the same corrugated ridges used in novelty 3D postcards, refract light to create a “dead spot” where an object vanishes.
• Hyperstealth has documented 13 variations of the material aimed at hiding personnel, tanks, aircraft and fixed installations, plus spin-off uses like holographic displays and solar-panel amplifiers.

Mechanisms of Light Refraction

Despite the “Quantum” branding, there’s nothing quantum-mechanical happening inside Quantum Stealth. The material relies on lenticular lensing — thin, ridged sheets of plastic lenses arranged so that light waves hitting the surface get refracted and redirected around whatever sits behind it. The same basic lens structure shows up in cheap 3D postcards and lenticular posters; Cramer’s innovation was figuring out how to layer and angle those ridges so the light bends far enough to erase a target rather than just create a flip-image gimmick.

The result, as CNET’s cameras showed firsthand, is a literal blind spot: a person standing behind the sheet at the right distance simply isn’t there anymore, replaced visually by whatever background is stretching across the gap behind them.

No Batteries, No Screens, Just Plastic

One of the more striking parts of the demonstration is how low-tech the material actually is. Quantum Stealth needs no batteries, no power supply, and no electronics of any kind — it’s paper-thin, lightweight, and according to Hyperstealth, cheap to manufacture at scale. That’s a sharp contrast to most “active camouflage” concepts floated over the years, which typically depend on cameras, projectors, or adaptive electronic skins.

The material works across visible light, ultraviolet, infrared, and shortwave infrared, while also masking thermal signatures and target shadows.

That multispectral performance is what separates Quantum Stealth from a novelty trick. Hiding something from the naked eye is one thing; hiding it from thermal and infrared sensors is the part that gets defense contractors’ attention, since modern targeting and surveillance gear increasingly hunts for heat signatures rather than just visible shapes.

The Catch: Standoff Distance and Viewing Angle

The prototypes CNET tested aren’t ready to become a wearable uniform anyone can throw on and walk around in. The effect currently requires a fixed standoff distance — often several feet — between the material and whatever it’s concealing, and the illusion distorts or breaks down at certain viewing angles. That’s the core engineering hurdle standing between Cramer’s lab demonstrations and an actual field-deployable cloak that a soldier could wear like the concealment gear covered in something like the Marine Corps Scout Sniper Course’s approach to cover and concealment.

Hyperstealth’s own materials describe 13 separate variations of the technology, each scaled for a different application — concealing a single person, a vehicle, an aircraft, or an entire fixed installation. The company has also shown off related optical spin-offs that come out of the same lens research, including holographic displays and amplifiers designed to boost solar panel output, the kind of crossover tech that echoes broader interest in things like solar panels mounted on a Tesla.

Significance of Military Angles

Hyperstealth’s business is camouflage, and Cramer built the company’s reputation designing pattern-based concealment systems long before Quantum Stealth became public. A material that defeats visible, UV, infrared, and shortwave infrared detection simultaneously — without a power source — would be a genuine leap for units whose entire job depends on staying unseen, the same world explored in coverage of elite special forces and other secretive military outfits. The patent filings give Hyperstealth legal footing to pitch the material to defense buyers now that the secrecy phase is over.

Cramer has been candid that the current sheets are a proof of concept, not a finished field kit — the standoff-distance limitation alone rules out a simple uniform swap for now. What happens next depends on whether Hyperstealth can shrink that gap between the target and the lens sheet without losing the effect, which is the detail worth watching the next time Cramer or the company puts out an update on Quantum Stealth’s progress.
