Quantum technology used to embed security in objects
Scientists at Lancaster University have developed a way to embed unique security codes into any type of device, using quantum technology to create nano-scale identities which they claim can’t be cloned.
The research, published in Nature’s Scientific Reports, is being commercialised via Quantum Base, a spin-out company from the university. Known as Q-ID, the device operates without passwords or counterfeit tags that can be imitated. According to the system’s inventors, this marks a significant leap forward from current security solutions.
“The invention involves the creation of devices with unique identities on a nano-scale employing…quantum technology,” said first author Jonathan Roberts, a Lancaster University Physics PhD student of the EPSRC NOWNANO Doctoral Training Centre. “Each device we’ve made is unique, 100 per cent secure and impossible to copy or clone.”
Q-ID uses an electronic measurement with CMOS compatible technology, which the Lancaster team says can be easily integrated into existing chip manufacturing processes. On top of the primary security function, the device could also provide the ability to track and trace objects across a supply chain.
