Interesting science popularization, Baidu has a good idea!
What is quantum
First of all, we have to mention quantum theory founder - Planck . As expected, quantum is very brain-burning...
Planck research pre-quantum VS research post-quantum Quantum (quantum) is an important concept in modern physics. means that if there is a physical quantity, if there is a smallest indivisible basic unit, this physical quantity is quantized, and the smallest unit is called a quantum. It was first proposed by German physicist M. Planck in 1900. can't read? Let’s give an example! We see the fish in the distance, which is black and black.
But when you zoom in, it looks like a fish, can be said to be the quantum of the fish school.
Associate researcher and popular science expert at the University of Science and Technology of China , and Yuan Lanfeng said: "When we count the number of people, there can be one person or two people, but it is impossible to have half a person or one third. When we go up the stairs, we can only go up one step or two steps, and we cannot go up half a step or one third." In short, "The things we can see and perceive in our lives, including the smallest unit of light and energy, can be called quantum."
What is quantum entanglement
Once upon a time, Einstein firmly believed that "God will not roll dice", and everything has certainty.
But according to the research in the next few decades, the truth is biased towards God can roll dice. microscopic world is indeed "probability" rather than "determined"; the "ghostly over-distance effect " that violates the theory of relativity also really exists.
Quantum entanglement is a kind of " ghostly effect of over-distance ".
Quantum entanglement is a phenomenon that occurs when particles affect each other in a particle system composed of two or more particles. The most special thing is that even if these particles are separated from each other in space, they can also affect each other.
Therefore, many people compare quantum entanglement to " telepathic ", Two people do not contact each other, and can also influence each other.
Netizens also have a variety of understandings of "quantum entanglement".
What is Schrödinger's Cat
The most famous cute pet in the history of science - "Schrödinger's Cat" - is actually just a thought experiment. Austrian The famous physicist Schrödinger proposed that if a cat is locked in a closed container containing a small amount of radium and cyanide, there is a chance of radium decay. If radium decays , it will trigger the mechanism to break the bottle containing cyanide, and the cat will die; if radium does not decay, the cat will survive. According to quantum mechanics theory, since the radioactive radium is superposition of decay and no decay, cats should be in the superposition of dead cats and living cats. Simply put, this is a cat that is both dead and alive.
Similarly, if you buy a fund, as long as you don’t look at it, it will be in a state of superposition of rise and fall... This fund that both rises and falls is the so-called "Schrödinger Fund"...
What is Quantum computing
As the saying goes, "If you encounter something, quantum mechanics will not be decided."
The meaning of quantum computing is to put it simply, it is a technology that uses the principles of quantum mechanics to perform calculations.Similarly, quantum computer is a hardware system that uses quantum computing. Quantum computing is a disruptive technological development direction with huge potential value, and has achieved rapid development in all aspects in recent years. Recently, the superconducting quantum computer " Qianshi " released by Baidu .
It integrates quantum hardware, quantum software, and quantum applications. The hardware platform is equipped with 10 qubit high-fidelity superconducting quantum chip, which can provide users with stable quantum computing services. Among them, the most core quantum processor (chip) is placed in a low-temperature device called the "Extremely Low Temperature Test Platform", and its minimum temperature is close to absolute zero (-273℃).
"It's like, the calmer you are, the more you will be, the faster you calculate." , director of Baidu Quantum Computing Research Institute, quipped in the explanation.
hardware is a core link, but hardware alone is not enough. Baidu Quantum was established in March 2018 and has successively released the first cloud quantum pulse system in China " quantity pulse ", the world's first cloud-based quantum machine learning platform " quantity paddle ", and the world's first cloud-native quantum computing platform " quantity ease ".
In addition, the "Qianshi" quantum software platform supports obtaining quantum computing power through cloud services and provides industrial-level quantum computing services. In order to simplify the entire process of deploying quantum hardware to quantum services, Baidu has also launched the world's first full-platform quantum software and hardware integrated solution "Qingxi". It is said that "Liangxi" can provide a series of services such as privatized deployment, cloud services, hardware access, etc., and has adapted to multiple mainstream quantum chips such as superconducting and ion traps, which can realize "plug and play" of quantum chips.
