In the past two days, Google and NASA jointly released a paper achieving quantum supremacy (also known as quantum advantage).
That is to say, in a certain computing field, it can complete calculations that are impossible for today's most powerful supercomputers - they claim to perform a calculation in 3 minutes and 20 planes, and the supercomputer summit takes 10,000 years.
Strangely, Google and NASA removed the paper shortly after it was released.
Regardless, this is breaking news for the field of quantum computing.
So, what is quantum computing.
For traditional computers, when its CPU process enters a field smaller than nanometers, all the theories it adapts to will no longer apply.
Yes, it is certain that Moore's Law will fail.
When classical computers enter smaller processes, a new field of physics will enter the field of vision of all scientists, that is - quantum physics.
In contrast to traditional computer binary which is either 0 or 1, qubits are either 1 or 0.
The two sentences are the same, please refer to the meaning: No one can beat Chinese table tennis, and no one can beat Chinese football.
Yes, qubits can be 1 or 0 at the same time. When they are entangled together, the states they can represent will increase exponentially, making it possible to instantly calculate millions of possibilities.
Cryptography, materials, medicine, and artificial intelligence are the areas where it exerts its power. In other words, even if quantum computing is realized, classical computers will still continue.
But when will it be realized?
In my lifetime!
This thing is as useless as controlled nuclear fusion.
How to control it, how to correct errors, there are a lot of problems waiting to be solved.
In China, in addition to major universities and Professor Pan’s team, Alibaba’s Damo Academy has begun to work on the software level of quantum computing (similar to operating systems.)
None of us know whether overtaking on curves can be realized, but studying this thing is a must-have for all major countries.
The purpose of this popular science chapter is to tell everyone that semiconductors are still the top priority in the future. Quantum computing... No way!
