BlackBerry Races Ahead of Security Curve With Quantum-Resistant Solution (techcrunch.com)
An anonymous reader quotes a report from TechCrunch: Quantum computing represents tremendous promise to completely alter technology as we've known it, allowing operations that weren't previously possible with traditional computing. The downside of these powerful machines is that they could be strong enough to break conventional cryptography schemes. Today, BlackBerry announced a new quantum-resistant code signing service to help battle that possibility. The solution, which will be available next month, is actually the product of a partnership between BlackBerry and Isara Corporation, a company whose mission is to build quantum-safe security solutions. BlackBerry is using Isara's cryptographic libraries to help sign and protect code as security evolves.
"By adding the quantum-resistant code signing server to our cybersecurity tools, we will be able to address a major security concern for industries that rely on assets that will be in use for a long time. If your product, whether it's a car or critical piece of infrastructure, needs to be functional 10-15 years from now, you need to be concerned about quantum computing attacks," Charles Eagan, BlackBerry's chief technology officer, said in a statement. Some of the long-lived assets include aerospace equipment, connected cars, or transportation infrastructure -- basically anything that will still be in use several years from now when quantum computing attacks are expected to emerge.

How is this better than AES-CMAC?
Quantum only affects asymmetric cypher's mainly used for key distribution as far as I know.
Symmetric cypher's like AES should be unaffected if you just up the number of bits a bit.
Since symmetric key ones are resistant, just increase the key length which is why there is a required 256 bit option for all AES entrants, you want to look at asymmetric key crypto. Here there are 2 main options available. The first is Lattice-based crypto and the other is Multivariate crypto. Both defeat Shor's algorithm which is the one to be worried about with asymmetric key crypto.
