Links on website: & vs. & ... different for Google? Duplicate Content?

ASP.NET MVC Helper made that on the an archive page like …

… we got these URLs in the HTML:

: [code][/code]

Breadcrumbs in :

<span typeof="v:Breadcrumb"><a rel="v:url" property="v:title" href="" title="dpa-AFX - News vom 10.11.2013">dpa-AFX - News vom 10.11.2013</a></span>

Now the big question:
Is an URL with & for Google search the same as the URL with & OR do I have 2 different URLs (= duplicate content)?

According to this it is different in Google Maps:

What is your opinion?

My opinion is that Googlebot will simply convert the & in a URL to &, like any browser would (except in the source code, of course). Sounds to me like basic functionality for a search engine spider, so I really wouldn’t worry about this.

Also, searching site: inurl:amp currently returns no results.
