According to Anhui Daily, Professor Pan Jianwei, executive vice president of the University of Science and Technology of China, a member of the Chinese Academy of Sciences and a founding school director of West Lake University, revealed the latest advances in optical quantum computing to the public in his first public lecture at West Lake University on September 5th: his team has achieved a quantum computing performance of more than 1 million times that of Google’s 53-bit quantum computer.
Quantum science has been developing for more than a hundred years to solve the major problems of information technology. Quantum computers can solve complex problems that traditional computers can’t solve and show quantum superiority. For example, the computing power of quantum computing increases exponentially with the manipulatable number of quantum bits. It takes 150,000 years to break down 300-bits using a trillion-bit classic computer, while a trillion-bit quantum computer takes only one second. Last October, Google developed a new 53-quantum bit processor that takes about 200 seconds to solve a task that a classic computer takes about 10,000 years to complete. “Just last week, we just completed a Bose sample of 50 photons, about a million times faster than Google’s Quantum Advantage.” Pan Jianwei revealed.
Pan Jianwei has long been engaged in quantum optics, quantum information and the examination of the basic problems of quantum resymnonsmics, and is an internationally influential scholar in this field. Earlier, Professor Zhu Xiaobo, a member of Pan Jianwei’s team, also said at the “Mozi Salon” organized by the Shanghai Research Institute of the Chinese University of Science and Technology that the team will achieve a 60-bit quantum computing system this year, surpassing Google’s 53-bit quantum computing level.
On October 23rd last year, Google published a paper in the British journal Nature claiming that its quantum calculators had achieved “quantum supremacy”. Sundar Pichai, Google’s chief executive, wrote that it had taken the company 13 years to make the breakthrough.
According to CCTV News reported in September last year, a number of British media revealed that technology giant Google (Google) an internal research report showed that its research and development of quantum computers in 3 minutes and 20 seconds, the completion of the traditional computer takes 10,000 years to deal with the problem, and claimed that the world’s first “quantum supremacy.”
According to the report, Google researchers set up a 53-bit quantum computer, codenumed “Hanging Suzuki.” The operation performed by the “hanging Suzuki” quantum computer is to prove that a random number generator meets the “random” standard. According to the report, even the most advanced traditional supercomputer in the world, Summit, takes 1 million times to sample an instance of a quantum circuit and takes 10,000 years to process, but the “hanging Suzuki” takes only 200 seconds to complete.
In fact, in addition to Google, international business machines (IBM), Intel and other enterprises are developing quantum computers, including IBM in early September, also successfully created 53-bit computers, IBM’s 14th quantum computer, is also the most computing power of the one, and plans to provide 53-level computers online for customers from October.
Google had expected “quantum supremacy” by the end of 2017 and at one point set up 72-bit computers, but instead studied 53-bit computers because they were too difficult to handle.
