 ### _"But won't quantum computing make AES irrelevant?"_ {#quantum}
 
-We are now entering an era where quantum approaches to breaking ciphers will advance along with more constructive applications: but the same laws of physics that apply thermodynamic limitations to information density will also apply at some level to limit the density of optical frequency wave superpositions... and so Schneier's inventory of information density requirements would still apply.

 Still we can assume we are headed, at some point, for an age in which quantum computing will require the redesign of encryption strategies at all levels.  Yet socially we will have years of advance notice before such technology creates a general vulnerability of full 256-bit AES: meaning that any insecurities from the Frankenwallet's perspective are still determined *only* by assurances of the integrity of keys themselves: i.e. how workflow software handles your **passwords**.
