Introduction of Quantum Chip
With the increasing requirements for nanotechnology, silicon-based chips will reach the limit of human science and technology in the near future, so if you want to continue to break through, there are only two aspects. One is to change the material of the chip, and the other is to change the type of chip. And structure. For example, the carbon-based chip we have been talking about is to change our silicon material into carbon nanotubes. Because of the superconducting properties of carbon nanotubes, the performance of carbon-based chips is more than 10 times higher than that of ordinary chips. However, the performance of quantum chips may exceed tens of thousands of times.
Break Through The Quantum Entanglement of The Speed of Light
We all know that the speed of light is the fastest speed we have found in the universe, and quantum entanglement and other properties are also considered to be a new way for humans to break the speed of light. We compare the circuit of a traditional chip to a road. The number of vehicles passing per second is its computing speed. However, the principle of a quantum chip is different. When testing quantum entanglement, we place the two quanta very far away. As long as one quantum changes, the other quantum will change accordingly. This is called quantum state entanglement.
In addition to quantum state entanglement, quantum also has a superposition state, which can also be said to be quantum entanglement caused by superposition state. Superposition state means that a quantum system can be in a superposition state of different quantum states. When you toss a coin, you don’t know this pattern before you toss it. It is not fixed. Only when the coin falls to the ground, you guess which side you will find which is facing upwards. Produce its form.
Quoting the famous "Schrödinger's Cat" theory once vividly stated: "A cat can be both alive and dead at the same time." In a quantum system, only when you determine the form of one quantum can you know the form of the other.
The Development of Quantum Chip Technology
In 2020, the field of quantum computing chip research will further increase. This new material and new method will promote the innovation of semiconductor devices. In the next few years, quantum computing technology will enter a critical period. The world's first commercial quantum computer was officially released by Canadian quantum technology company D-Wave on May 11, 2011. In 2017, it was composed of 2000 qubits to solve problems such as optimization, network security, machine learning, and sampling. The processor D-Wave 2000Q, this model is about 1000 to 10000 times higher than the highly professional algorithm at the time in the actual test.
Application Prospects of Quantum Chips
In addition to ultra-high performance, quantum computers using quantum chips also have encryption methods that are currently almost impossible to crack. The information after quantum encryption is not measurable like radio waves because of the characteristics of quantum entanglement and superposition state , You can’t accurately measure the shape of each quantum. Once the quantum shape is measured, it will change. On the contrary, if a quantum computer is used to decrypt the current communication information, with the support of tens of thousands or even a million times the performance, the information that may have taken one year to decrypt before can now be simulated in only one minute. This ultra-high-speed computing power will provide powerful computing power for future AI intelligent systems.
