Subject Searching
I chose the Computer Science subject and selected the Informatics guide.  I then chose the EBSCOhost databases.  I then conducted a boolean search for Encryption AND Security AND Quantum.  This returned 89 results.  I selected the Full Text and Peer Reviewed options which narrowed it down to 46 results.  I did not change the date range since it was already 1999 to 2020.
I found the following source which provided me with a subject “DATA encryption” to search.  (Simmons., 2009)
The DATA encryption subject resulted in 3,834 results.  I then located an article that mentions quantum computing and got an additional subject “QUANTUM computers” (Atkinson., 2020)
Searching for the subjects DATA encryption AND QUANTUM computers returned 14 results.  Limiting to Full Text Peer Reviewed articles returns one article.  This article is relevant and useful for me so I recorded it for later. (UNRUH., 2015)
These searches proved useful since it taught me a new way to search.  I will have to do more searches with different databases and subjects to find more information though.  Unfortunately I only found one new source, this one is an interesting one I hadn’t seen before.

Citation Trace
I used the article I found above for my citation trace.  I found one citation titled “Uncloneable encryption” (Gottesman., 2003).  The original link in the citation is broken, but I was able to locate the article anyway.  This is a good subject about how quantum cryptography can be constructed in a way that it cannot be copied or recorded except by the intended recipient.  This is something I hadn’t thought about before, so the citation trace was incredibly useful for me.
