The posited pattern matching capabilities of quantum computing may have a couple of different applications in access control.
Biometrics would likely benefit from improved abilities to match and compare. At the moment we don’t actually compare, for example, the fingerprint originally registered with the fingerprint presented. Biometric matching must be done on the basis of constructs and representations of biometric data that lose a great deal of information in the symbolization process. The complexity and detail of whatever biometric is used is reduced to a rather small number.
