Beijing time on the 15th, according to foreign media reports, French physicists claim that they have designed a device that can capture photons, this photon capture device is only 2.7 cm (1.1 inches) large, can produce photo to disappear from photons. Monitoring throughout the process.
In 1927, Albert Einstein imagined such a box in which light could be captured, and individual light particles or photons could be released in theoretical experiments to measure the relationship between matter and energy. Photons can be thought of as the ultimate particle in the physical world. When the incandescent bulb is on, 1000 trillion photons are released every second. But once you see the photon it disappears, because the photon consumes the energy that sustains it when it comes into contact with the retina.
Jean Michelle Raymond of the French National Centre for Scientific Research is one of the team members who invented the box. He said: "Photons can be detected very easily. Open computer screens have every second. The photons are released. But you can only detect the photons once. Although we can now analyze the photons in real time while they still exist, this is still an afterthought."
The box consists of a recess, surrounded by the most reflective material. This super-conducting mirror allows the captured photons to remain in 1/7 of a second. This time does not seem to be too long, but in such a short period of time, the distance of free photons can reach 1/10 of the distance between the moon and the earth.
In the conventional research method, the number of photons is calculated by the light detector absorption and the energy lost after the photons collide with each other. But this collision can destroy photons, so you need to find a penetrating photon calculator. The French research team published their research report in the British journal Nature on Thursday, researchers said that photons can be successfully captured when helium atoms flow through the box.
Photons have an electron region that can slightly change the energy level of an atom, but in experiments, atoms cannot absorb energy from this electron region to generate energy transitions. When an atom traverses the electron region of a photon, it causes a time delay in the movement of electrons around the nucleus. This time delay can be calculated, and modern atomic clock technology can solve this problem, because the orbit of the electrons can provide precise time like the pendulum of the clock.
A quantum physicist at Ulm University in Germany and Ferdinand Schmidt Keller, also commented in the journal Nature, said that the research of French scientists is far from true quantum research. The work is still in the experimental stage. If a real quantum computer comes out, even today's supercomputer is in the same position as the abacus in front of the computer. Quantum computers do not use the 01 binary information storage mechanism, but on the basis of the principle of super-quantum state change. The change of quantum state is a superposition mechanism that occurs when the atomic energy level transitions or falls.
The minimum unit of quantum computer information storage can be 0, or 1 or both 0 and 1. This storage method can make the data storage of the computer amazingly improved, but only when managing and reading data. To take advantage of it. Although quantum storage research has just begun, scientists have discovered that photons, atoms and ions can be used as storage media for quantum computers. Schmidt Keller said: "Experiments by French scientists have shown that changes in the state of captured photons can completely control the atomic storage of information."
Wheel Dresser
(1) Diamond pen dressing grinding wheel: According to the size of diamond particles and their distribution in the pen, diamond pens can be divided into several types, such as chain and powder. The alloy with strong bonding force is used as the bonding agent, so the diamond grinding wheel particles are not easy to fall off during use, so there is no need to repair the grinding process.
(2) Grinding wheel dressing by rolling method: Diamond grinding wheel dressing by rolling method. Grinding wheel drives the rolling wheel at the speed of 1~2m/s by reducing the speed
Made of, carbide or abrasive) rotary. The pressure of rolling wheel applied to grinding wheel is about 3~5MPa, grinding the surface of diamond grinding wheel
Make the abrasive particles fall off. The grinding wheel dressing by rolling method has better cutting performance and lower cost, but the surface roughness of the grinding part is rougher and rolling
Damage, short life, easy loss of precision. Therefore, this dressing method is mainly used for forming grinding with small batch size and low precision.
Green silicon carbide or ceramic white corundum is used for dressing. Dressing ring is the first choice for dressing diamond grinding wheel or CBN grinding wheel. It is sharp in dressing, not easy to remove sand and has high dressing efficiency.
