Quantum computers in the full sense may come earlier than expected. According to foreign media reports, scientists at Griffith University and the University of Queensland in Australia said on Monday they had discovered the first in history to simplify the creation of the quantum "Fredkin logic control gate" approach. At present, their research results have been published in the science magazine "Science Advances". Raj Patel, a professor of quantum dynamics at Griffith University Center, explains that a quantum computer works just like a normal computer, including a logic gate in programming. However, quantum computers also contain quantum logic gates that repeatedly exploit quantum phenomena. Patel said, for example, it's like building a huge wall with lots of small bricks, and large-scale quantum circuits that use a lot of logic gates and the same big brick if built The number of bricks required for the wall will be much less. By simplifying complex quantum operations, the less logic gates are needed to develop a quantum circuit, and as a result, scientists can more easily create a quantum computer. According to reports, Patel and his team experimented with a special type of quantum logic gate called the "Fredkin Gate." The logic gate works that two qubits can be swapped based on the value of the third quantum dot. Patel's experiment demonstrated how to use photons and non-small logic gates in a more direct way to create large-scale quantum circuits. "The Fredkin logic gate can also be used to compare two sets of quantum dots directly to determine if they are the same," said Timothy Ralph, a co-researcher from the University of Queensland. "This makes the discovery Not only is it useful in computing, it also provides a secure foundation for some quantum communication protocols that compare characters in two groups. " Quantum computer performance is generally considered to be orders of magnitude faster than today's traditional computers. Since the concept of the 1980s, computer scientists and physicists have made quantum computers their ultimate goal. However, due to the natural instability of quantum dots, mankind has so far failed to make major breakthroughs in this field. Earlier this month, a recent paper in Science magazine showed that for the first time in quantum computing Shor's algorithm was implemented in a scalable way. According to foreign media Engadget, computer scientists at MIT and Innsbruck University assembled a 5-qubit quantum computer that will be able to use the Shor algorithm to figure out the prime factorization of number 15. They developed a quantum computer prototype and then used a series of ions to perform a Shor algorithm on four qubits by means of laser pulses to break up the numbers and a fifth qubit to store and output the results. The result is that this computer not only calculates the solution more efficiently than existing quantum subsystems, but also scales the relative ease. This is a very big motivation for building quantum computers and for studying new quantum computer algorithms. ChangZhou FENGJU Machinery Equipment CO., LTD , https://www.fengjumachinery.com
