Agree this post was a little longer than what I usually write, obviously I was't going to achieve a comprehensive overview but I wanted to touch on as many of key points as I could without going overboard. I tried to make up for length by incorporating some humorous elements in the second half and limiting math equations to the minimum necessary for elementary concepts. It reads better if you use the soundtrack :) The detailed challenges of extending coherence time are mostly hidden to those whose primarily research tools are search engines and textbooks such as myself. This is the realm of proprietary tech, all I can do is speculate based on the credibility of those making large investments in the space that those in the know see potential.
