Quantum computing has always been confusing. You need to read a lot of technical materials to understand this technology. However, quantum technology may become a reality within ten years, which will have a huge impact on the industry. Currently, most encryption algorithms (especially public and private keys) are feasible because their mathematics makes it difficult for conventional (non-quantum) computers

optical fiber channels, the reasonable cost is about 1 Gigabit or two thousand MB, which costs about 50 thousand to 60 thousand USD. From another perspective, although the new iSCSI-based SAN solution only costs about $20 thousand to $30 thousand, its performance cannot be compared with that of the fiber channel. The major difference in prices is that iSCSI technology uses a large number of production of gibit Ethernet hardware, while fiber channel

I realized that this was a breakthrough thing, and went back soon to sum up the idea, in June 96 to apply for this aspect of the United States patent. July 6, 1999, the United States Patent and Trademark Office approved the patent number of 5,920,859, to me as the only inventor of the patent. At about the end of 96, two graduate students at Stanford University's computer department thought of the same solution, and they later created a search engine called Google, and Google's website still says
