But at a time when people are debating whether Google really has quantum hegemony and what the real meaning of quantum hegemony is, the quantum hegemony thesis that wrinkles a pool of spring water has disappeared mysteriously. According to the subsequent news from NASA, it was possible that the paper was mistakenly sent to be completed, so it was subsequently deleted by itself.
Googles claim of quantum hegemony is not the first time
Whether this paper oolong is a careless loss or a carefully arranged fire test is not listed for the time being, but during the existence of the paper, the two points expressed by Google are very clear.
Second, it is Google, not any other country, region or enterprise, that has become the leader of quantum hegemony.
In fact, in the past one or two years, Google has made a lot of milestones in the quantum related topics, which are true, false and real, and many of them are more dry goods than the lack of reference papers.
For example, on March 5 last year, Google announced the launch of a 72-bit quantum chip, Bristlecon, to break through the quantum hegemony; at the end of July last year, Google released Cirq, an open source library of Python that is supposed to be used for quantum computing, and once again highlighted the label enough to prove quantum hegemony.
For these milestones, scientists from all over the world quickly calmed down after a period of excitement, excitement and tension. On the one hand, they affirm Googles investment, exploration and harvest in this area, on the other hand, they also point out realistically that there are two key uncertainties in either Bristlecon or Cirq.
Firstly, it is difficult to verify the comparative conclusion between quantum computer and traditional over-computing. Secondly, the error rates of various quantum processors developed and published by various countries and research institutions are not stable in readout and logical operation. As some scientists have pointed out, a fast but error-prone quantum computer is far from enough to replace the traditionalovercalculation.
There are two key uncertainties in quantum hegemony
When Google announced that it had quantum hegemony by publishing Bristlecon, Patrick Hayden, a famous quantum physicist at Stanford University and co-convener of Q-FARM project, said that quantum hegemony was only a vague milestone.
Hayden pointed out that the so-called quantum hegemony is a goal concept put forward in the process of quantum computer research and demonstration, that is, if we can prove that quantum computer has far more computing power than the best over-calculation, we can realize the hegemony of quantum computer over traditional computer.
However, in view of the fact that neither of the two key uncertainties has been proven to be effective breakthroughs so far, no research or commercial development agency has so far been able to say responsibly that its results are sufficient to conclusively and steadily replace overruns in a practical area.
The so-called quantum hegemony will naturally fail to land for the time being.
Therefore, while affirming some scientific achievements, we should also explore and try in the field of science and technology and adopt a more scientific and prudent attitude: science needs not only bold hypothesis, but also careful verification, but also patience, caution and time. Science is risky, and scientific exploration allows repeated trials and periodic setbacks. It is necessary to be too impatient.
