1. There must be such a subject as black hole simulation. I heard a report in 2009, that's what I did. I have other classmates doing it. Except for the celestial bodies; High energy physics. My friends are doing or have done scientific research requiring large-scale calculation, including: behavior of biological macromolecules, gene sequence analysis, gene expression pattern analysis, energy bands of various catalysts, finance, liquid properties, superconctors and other materials, geological activities, meteorology... Er... Such a list of discoveries should give me a scientific calculation that doesn't require a lot of computing power. I feel that many teachers are very greedy. The more computing resources, the better

According to reports, recently some media reported that China is building a large research center for the application of quantum technology, and the ultimate goal is to build a quantum computer with computing power millions of times that of all computers in the world
experts say that quantum computing makes use of the property that subatomic particles can exist in more than one state at any time, which makes quantum computers much faster than current computers and lower energy consumption. It is expected that this huge increase in computing power will push artificial intelligence and other emerging technologies to new heights
netizens expressed the hope that the research and development of quantum computer can be completed as soon as possible
4. It's not as the title says,
in short,
quantum computer is to replace the original ordinary bits with quantum bits
from the physical level, quantum computers are not based on ordinary transistors, but use spin direction controlled particles (such as proton nuclear magnetic resonance) or polarization direction controlled photons (mostly used in school experiments) as carriers. Of course, in theory, any multi-level system can be used as the carrier of qubits
from the perspective of calculation principle, the input state of quantum computer can be either discrete eigenstate (like traditional computer) or superposition state (probability superposition of several different states). The operation of information is extended from traditional logic operations such as "and", "or", "and" to any unitary transformation, and the output can also be superposition state or an eigenstate. So quantum computer will be more flexible and can realize parallel computing< If you want to explain the details, it's a bit troublesome. I'll give you some key words to look up:
1. Quantum state
2. Quantum superposition
3, qubit
4, unitary transformation
5, quantum logic
6, quantum gate (corresponding to traditional logic gate, In fact, it is some special positive transformation)
7, quantum algorithm, quantum algorithm (of course, quantum computer can also realize the traditional algorithm)
8, and then on how to realize from the physical level, it is best to start with quantum optics, because polarized photons are the simplest
in depth:
ordinary digital computers run on binary systems of 0 and 1, which are called "bits". But quantum computers are far more powerful. They can operate on qubits and can compute values between 0 and 1. Suppose an atom placed in a magnetic field rotates like a top, so its axis of rotation can point up or down. Common sense tells us that the rotation of atoms can be up or down, but not all at the same time. But in the strange world of quantum, the atom is described as the sum of two states, an upward turning atom and a downward turning atom. In the wonderful world of quantum, every object is described by the sum of all the incredible states
imagine a string of atoms arranged in a magnetic field and rotating in the same way. If a laser beam is shining on the top of the atoms, it will jump down the group of atoms and quickly flip the rotation axis of some atoms. By measuring the difference between the incoming and outgoing laser beams, we have completed a complex quantum "calculation", involving a lot of rapid spin movement
from the perspective of mathematical abstraction, quantum computer performs the calculation with set as the basic operation unit, while ordinary computer performs the calculation with element as the basic operation unit (if there is only one element in the set, quantum calculation is no different from classical calculation)
take the function y = f (x), X ∈ a as an example. The input parameter of quantum computation is the domain a, and the output domain B is obtained in one step, that is, B = f (a); The input parameter of classical calculation is x, and the output value y is obtained. The range B can only be obtained by multiple calculations, that is, y = f (x), X ∈ a, y ∈ B
quantum computer has a problem to be solved, that is, the output range B can only randomly take out a valid value y. Although the number of elements in output set B is much less than that in input set a by directing the unwanted output to an empty set, it still needs to be calculated many times when all the valid values need to be taken out.

5. Particle vision is the world's top miner, focusing on the IPFs field. At present, the main business is the sale of mining machinery and computing power!
6. In the future, Z5 mobile phone will open the function of binding particle mining cloud app users in the particle wallet through OTA upgrade. Through the binding of particle mining cloud, the contribution value of particle mining cloud users in the whole network (contributed storage space) can improve the number of particles (reflected in the mobile particle wallet). The smaller the storage space users use, the larger the storage space users contribute to the whole network, and the greater the user's contribution value (the greater the computing power), so that users can improve their particle number and allocate more star diamonds. The distributed / shared storage function of particle mining cloud (not mining, just shared storage space) is the key feature of generating the number of particles and allocating to more star diamonds.

The formula is e = mc2-mc2, C is the speed of light, M is the mass in motion, and M is the mass at rest
the kinetic energy theorem is applicable to both linear and curvilinear motion of objects; It is suitable for constant force and variable force; The force can act in sections or at the same time. As long as the positive and negative algebraic sum of each force can be obtained, this is the advantage of kinetic energy theorem
The sum of the work done by all external forces plus the sum of the work done by all internal forces is equal to the change of the total kinetic energy of the particle system. It's the same as the kinetic energy theorem of particle
extended data:
momentum theorem ft = mv2-mv1 reflects the cumulative effect of force on time, which is the integral of force on time. The kinetic energy theorem FL = 1 / 2mv22-1 / 2mv12 reflects the cumulative effect of force on space and is the integral of force in space
The total distance and times of reciprocating motion can be calculated by using kinetic energy theorem instead of considering the specific motion process. If Newton's law and kinematic formula are used to solve the problem, the method of sequence summation must be used8. For larger charged objects, gravity should be calculated, such as small balls and st. If it is a micro charged particle, it is generally not used, such as electrons and protons.
9. Nimff has low combat ability and high emotional and computing ability. The only direct attack method is paradise song. After evolution, particle jamming system is added, but it can't be used for a long time; It seems that the energy is not strong enough]
astraya has low computing power, high fighting and emotional ability [in fact, it's a fool, but it's very strong]
others are unknown, but Meilan (Icarus of the black) is better than Icarus of the early generation, much worse than Icarus of the evolution
Habibi is better than nimff. It's worse than Icarus and astraya. Rihe is powerful, but he has no strong defense means and armor. He should be worse than nimfu. CAOS is against the sky now, and he is the strongest so far. Because he has absorbed all Melan's corpses, he has Icarus, nimfu and astraya and all the abilities of siren. He even has three pairs of wings (his own blade wing, his own wing Icarus's variable wing and nimff's transparent wing); Siren (underwater combat angel) is absorbed by CAOS after second killing. It only knows that its anti water pressure ability is better than all angels (CAOS can't be broken at 8000 meters, but only wings can move, and siren can move at will). Oregana is used for medical treatment, but it is quite dark
