It was a good read: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;arxiv.org&amp;#x2F;abs&amp;#x2F;1710.05867&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;arxiv.org&amp;#x2F;abs&amp;#x2F;1710.05867&lt;/a&gt;&lt;p&gt;They&amp;#x27;ve had real hardware for a while, though, and they have 5-qubit and 16-qubit machines that anyone can try via IBM Q experience.&lt;p&gt;So this is 100% legit as far as I&amp;#x27;m concerned.</text><parent_chain><item><author>darawk</author><text>The article appears to be saying that they are offering an &lt;i&gt;actual&lt;/i&gt; quantum computer as a service, but as I recall, their previous offering was a &lt;i&gt;simulation&lt;/i&gt; of a quantum computing environment.
