Quantum digital printing

If you think that the internet of things is only done with ultra-simplified circuits and that quantum technology is an extremely complicated and futuristic thing, it’s best to pay close attention to this chip.

It has been thought to function as an anti-counterfeit label, which can be incorporated into products to attest its origin and authenticity.

The novelty is that it does this using a quantum technology, which makes the chip itself virtually immune to fakes.

On an atomic scale, quantum physics amplifies these irregularities, making it possible to create a “fingerprint” of the material that can be incorporated into simple electronic devices and optical labels – essentially a quantum digital print.

Authentic or fake

The team demonstrated how the technique works through a mobile application that can read whether a product is authentic or fake using the camera itself.

The idea is that when the technology is adopted commercially, consumers themselves can quickly check whether a product is authentic or counterfeit: The application reads the number on the label and checks the manufacturer’s database to see if it is a valid product.

The team claims to want the new chip to hit the market in early 2018.
