How can I make a page for post formats (specifically quotes) in wordpress 3.5

Because post formats are a taxonomy, WordPress handles the archive index page automatically, using the slug type as the taxonomy, and the post format type itself as the taxonomy term; e.g:

www.example.com/type/quote

If you want to customize the appearance of this taxonomy archive index page, you would modify the appropriate taxonomy template file, as per the Template Hierarchy:

  • taxonomy-post_format.php for all post format types
  • taxonomy-post_format-post-format-quote.php for the quote post format type.
