I actually saw this problem today, and the day ... In this major, I have been fortunate to hear that the group of their experiments will come to (CHE) to answer (Dan) a bit.

Before the Chaoyang Lu Group in the group will be in the time of the brother is doing this, I am a professional undergraduate, before I saw them paper hair, there are news, but also with roommates vomit slot. But the experiment itself is OK, Zhong Ke in this area is indeed the world's leading, so combined with some other disciplines to make some experiments are still very interesting, such as before there has been the use of quantum computing and biological combination of experiments, do not know when to send a paper.
Watch out for the news. Map below。 This picture is really relevant, not write the news casually. Why do you say that, because this experiment is abstracted out really is this diagram so simple.

The main content of this experiment is how to achieve the most basic machine learning (if you do not have to remember that year seniors are wrong):
The focus of machine learning is to predict new cases with some known answers.

The dots in blue indicate one case, and the red dots indicate a different case. So give a new point, how to tell if it belongs to the blue category or the red one?
The answer is to ask for distance. (in the classic case seems to be looking for new points ah, to determine the new case ah, a variety of complex balabala)

Then the experiment they do is to abstract how to find the distance between the two vectors .

This "first step in the important and interesting subject of quantum machine learning" is very pertinent. To put it bluntly, this is a very simple mathematical problem that is done by means of quantum computation. What's the big data hat? I think it's a suspicion that the news is making eyeballs.

So personal opinion :
This experiment itself is not a breakthrough, just buckle on the "machine learning" hat, did a pioneer. But there is little advance in the real problem of quantum computing.
This paper seems to be a bit of water (NN, black home school is not very good), but quantum computing is now a lot of papers are in the implementation of the algorithm Ah, try to calculate something. The content looks simple, but it's still a lot harder to achieve . You think a few photon entanglement is the world's leading, you now do a 6-bit 8-bit classic CPU what is it? In quantum computing you are Daniel.
But the individual is less interested in this kind of experiment is the main content of quantum computers to make, what can do? and not how to make it as soon as possible?

The students who are going to lose their jobs have let you down, and I bet my college classmates when I can make a quantum computer, the standard is 100 bit, time is 50 years. So I want this thing to work, I can only say, the Lifetime series. Now research is also diverted to play the classic computer/(ㄒoㄒ)/~~
