It should be something like:
The most important things that were wrong with the above code: the "and" between author names, the comma after the key (first line), and the extra braces around the TeX code for superscripts (I chose to use
\textsuperscriptsince you're superscripting text, but you could easily put math mode in there as well provided it's inside braces so as to expand directly).
I say "something like" because there are still a number of problems with this. (1) There is a number, but no volume; (2) This is not a journal article, it's an inproceedings. There are others.
