About Quantum Base

Quantum Base is a quantum science company creating a new global standard in authentication through its patented Q-ID solution - unbreakable and non-replicable authenticity tags that can be applied to a vast array of products, significantly mitigating counterfeiting.

The technology underpinning Q-IDs harnesses randomness at the atomic level, and this volume and variation ensure that there is virtually an infinite number of combinations that can be created. The Q-ID is practically impossible to replicate using even the most advanced available technology.

Q-IDs can be applied to almost any print line and can be entirely non-intrusive to a product's existing design, meaning that they can be utilised in a vast number of end markets. The authentication process to identify printed tags is undertaken using existing and unmodified smartphone technology, providing easy authentication and proven security for global brands, governments and consumers.
