Quantum communication is hot: China will use 15 years to build a world-wide quantum Internet

According to the Voice of China "National News Network" report, at the "2016 China Science and Technology Communication Forum" held yesterday (5th), Pan Jianwei, an academician of the Chinese Academy of Sciences, said that China will use 15 years to build a quantum Internet of heaven and earth, and strive for this year. The completion of the construction of the "Beijing-Shanghai trunk line" project fiber.

On August 16 this year, China successfully launched the world's first quantum science experimental satellite, the first time in the world to achieve quantum communication between satellite and ground. Pan Jianwei, an academician of the Chinese Academy of Sciences, said that an important application of quantum information science is quantum computing, which can achieve a leap in computing power. "The equations that require the solution of the 24th power of the 10th, using the current 'Taihu Light' computer, take about 100 years to calculate the time, but with a trillions of quantum computers, it takes about 0.01 seconds."

Pan Jianwei also gave a timetable for China's quantum computing research: after five years of planning, the coherent manipulation of 50 qubits will be realized, and the computing potential will surpass the supercomputer “Taihu Light” ranked first in the world in June this year; In the 15 years or so, we will build a future Internet with quantum communication security, namely Quantum Internet. "At present, we are also constructing a wide-area quantum communication network. We hope to connect Beijing and Shanghai at the end of this year. The length of the fiber is about 2,000 kilometers. It will promote research in the field of quantum communication through technical verification and application demonstration."
