Many of you may be thinking that all of this is nice, but we ourselves are surely decades away from being able to use a quantum computer, let alone design neural networks on it. While healthy skepticism is always nice, it does not do justice to the efforts of contemporary researchers, scientists, and businesses working around the clock to bring such systems to life. It may surprise you to know, for example, that anybody in the world with an internet connection today has free access to a quantum computer, using the link right here (courtesy of IBM): https://quantumexperience.ng.bluemix.net/qx/editor.
In fact, researchers such as Francesco Tacchino and his colleagues have already used this service to implement quantum neural networks for classification tasks! They were able to implement the world's first quantum perceptron, similar in spirit to the perceptron...
