| |DECEMBER 20218HONEYWELL-BACKED COMPANY IS GOING TO SELL SUPER SECURE QUANTUM ENCRYPTION KEYIN FOCUSBY CEO INSIGHTS TEAMQuantum computer software firm Cambridge Quantum announced it is going to launch a platform that can generate super secure cryp-tographic keys and sell them as a commercial product.The startup based in UK, this year became a wholly owned subsidiary of Quantinuum, a quantum computer hardware and software company in which Honeywell International Inc has a 54 percent stake. Cambridge Quantum uses the quantum computer to generate a particularly random encryption key.The quantum computing-generated offering is for encryption keys that Quantinuum and is designed uniquely and can't be predicted, a milestone in using high-tech computing for a practical business prob-lems. Traditional computers already generate en-crypted keys, but Quantinuum says it takes security a step further with vastly improved randomly gener-ated keys that are essentially helpful in hacking by conventional computers.Also, Quantinuum said the generation of random keys is a solution that's relatively easy for these new devices as it finds into the essence of quantum phys-ics in which a particle can be in multiple states at one time. Once the particle is steady, though, it col-lapses into one, random value and loses its quantum properties.The other aspect of quantum computing that makes it essentially fit for deriving random keys is entanglement, the term describes a characteristic of quantum physics in which particles connect with each other at a distance and take on the same properties. This phenomenon can't be replicated by a computer, which are limited by electric currents being switched to either on or off. Hence, Quantinuum only needs three high-fidelity quantum bits, or qubits, so that it can create a pool of random numbers and symbols from which the keys are made.Honeywell owns 54 percent of Quantinuum, has said the business will generate sales of about $2 bil-lion by 2027.
