examples are in the how-to guide complete with pretty screenshots.<p><a href="http://www.bristol.ac.uk/physics/research/quantum/qcloud/project/tutorial.pdf" rel="nofollow">http:&#x2F;&#x2F;www.bristol.ac.uk&#x2F;physics&#x2F;research&#x2F;quantum&#x2F;qcloud&#x2F;pro...</a>

Can an optical physicist comment on how the phase-shifting is accomplished? What do they mean by &quot;phase&quot;? (I would have expected this to mean polarization phase, but this chip seems to be based not on polarization but on relative phase shift?)<p>Also, that CNOT gate is… weird. How can post-selecting scale, if each CNOT gate in the circuit reduces the chance of a successful run by 89%?<p>Another also, the interpretation of the CNOT gate given in the tutorial seems reversed – photon mode 1 corresponds to control input <i>1</i>; mode 2 corresponds to control input <i>0</i>, at least according to the simulator.

It incorrectly binds touch event instead of click events for my PC.<p>If anyone else runs into this issue, you will need to bind the events from the javascript console:<p>gc.addEventListener(&#x27;mousemove&#x27;, mouseMoved, false); gc.addEventListener(&#x27;mousedown&#x27;, mouseDown, false);

&gt;&quot;If quantum computing does become a practical technology, there will be a relatively small number of quantum computers, which people will access remotely.&quot;<p>&#x27;I think there is a world market for about five computers.&#x27;
