white buffalo jewelry wholesale Summary: In a small laboratory located in a secluded countryside in the north of New York City, it is entangled with intricate pipelines and electronic equipment under the ceiling. This pile of seemingly messy equipment is a computer. It is different from any computer in the world, but a milestone device that is about to create a historic, quantum computer.
On May 3, 2017, a heavy news in the scientific and technological industry: The world's first optical quantum computer that surpassed the early classic computers was born. This "world's first" is a real "Chinese -made", which is a result of Professor Pan Jianwei and his colleagues of the University of Science and Technology of China. The results of the research group of Professor Wang Haohua from Zhejiang University have broken breakthroughs.
If the speed of traditional computers is a bicycle, the speed of quantum computers is like aircraft. In the past few months, IBM and Intel have announced that they have manufactured 50 and 49 quantum bitter computers. Some experts point out that within ten years, the computing power of quantum computers may catch up with the current supercomputers.
At the American Physical Physics Year Conference held in Los Angeles on March 5, 2018, Google quantum AI laboratory research scientist Julian Kelly reported that the Google team was testing a 72 quantum Bit universal computers. However, this is just a 72 quantum bit. Developed at this speed, the magical power of quantum computers soon will make people's fearful.
So why do you say that quantum computers can easily crack Bitcoin, what is going on?
It to solve the current RSA password system that is commonly used, it takes 600,000 years to use the current largest and best supercomputer, but using a quantum computer with a considerable storage function, it only takes less than 3 hours! In other words, from electronic computers to quantum computers, the ability of the entire human computing power and processing big data will occur from tens of thousands or even hundreds of millions of times. In the face of quantum computers, the traditional electronic computer we was proud of is equivalent to the previous abacus, which looks bulky and old!
Although the Bitcoin protocol uses asymmetric cryptocurrencies, it uses the corresponding public key to verify the transaction signed by the private key to ensure that Bitcoin can only be used by the legal owners. It is not feasible to use the current available computer forced private key and the public key, but quantum computers can solve the problem of asymmetric cryptocurrency.
It the regulations of Bitcoin are to handle the block to add the blockchain, and the other block is abolished. For example, this is like 51 people in a book book say that you have deposited 100 yuan in the bank, and 49 people say that you have deposited 50 yuan. In this case, a small number of blockchain algorithms obey the majority. Think that you have saved 100 yuan real, and 50 yuan is fake. So once a miner has 51%of the computing power, other subsequent miners will not be able to continue to get Bitcoin.
andersen cheng, co -founder of a British network security company, he said that the day when quantum computers were put into use, Bitcoin will end. What do you think?
small jewelry boxes wholesale To put it simply, the computing power of quantum computers is too strong. You can even say that in the future, there may be a quantum computer computing capacity that exceeds all ordinary computers around the world, and then such a powerful computing power can achieve the task that could not be completed before, such as passing the poor to poverty. To cracked the Bitcoin wallet, that is, the Bitcoin purchased in your hands will be easily stolen. Do you think it will collapse?
