Description

Technical Field

[0001] This design involves quantum entanglement state, and in particular, a demonstration device for displaying quantum entanglement state. It belongs to the category of optical science education instruments. Background Art

[0002] The concept of quantum entanglement was first proposed by Einstein, Podolsky and Rosen in 1935. They explored the completeness of quantum mechanics through the EPR paradox, which led to the study of quantum entanglement. When several particles interact with each other, the properties of each particle have been integrated into the overall properties. It is impossible to describe the properties of each particle separately, but only the properties of the overall system can be described. This phenomenon is called quantum entanglement.

[0003] In quantum mechanics, when particles are in a quantum entangled state, their spin directions cannot be determined individually. This is because in a quantum entangled state, a special correlation is formed between particles, so that the state of one particle (such as the spin direction) cannot be described independently of the state of other particles. This correlation causes the spin direction of the particle to be in a superposition state, that is, it contains two possible directions, up and down, but the specific direction is uncertain until it is measured.

[0004] When two particles are in an entangled state, if the spin direction of one particle is measured, the result will instantly affect the spin direction of the other entangled particle. For example, if the spin of the first particle is measured to be up, then the spin of the second particle must be down; and vice versa. This phenomenon fully demonstrates the non-locality and indivisibility of quantum entanglement, that is, no matter how far apart the two particles are, the measurement of one particle will instantly affect the state of the other particle.

[0005] With the development of quantum mechanics and quantum information science, more and more people are beginning to understand and pay attention to the phenomenon of quantum entanglement. Through various popular science activities, media reports and the efforts of educational institutions, the public's awareness of quantum entanglement has gradually increased.

[0006] Popularizing science about quantum entangled states still requires continuous efforts and innovations, especially how to popularize its profound and mysterious principles. This has become a difficulty in popularizing science about quantum entangled states. How to make accurate, popular and intuitive demonstrations remains a problem. Summary of the invention

[0007] In view of this, it is necessary to provide a demonstration device that can more accurately and intuitively display the specific principles of the quantum entangled state and vividly and interactively display the quantum entangled state.

[0008] A demonstration device for displaying quantum entanglement states includes a booth, a quantum distribution demonstration light strip, a left quantum spin demonstration box, a right quantum spin demonstration box, a left electromagnet group, a right electromagnet group, a left magnetic fluid, a right magnetic fluid, a button, and a rocker. The quantum distribution demonstration light strip is located above the booth, fixed on the center line of the booth, and is divided into two parts and connected to the left quantum spin demonstration box and the right quantum spin demonstration box respectively; the left quantum spin demonstration box is fixed on the left side of the center line of the booth; the right quantum spin demonstration box is fixed on the right side of the center line of the booth, and is symmetrical with the left quantum spin demonstration box on the center line of the booth; the left electromagnet group is in the booth, located at the bottom of the left quantum spin demonstration box; the right electromagnet group is in the booth, located at the bottom of the right quantum spin demonstration box, and its position is symmetrical with the left electromagnet group on the center line of the booth; the left magnetic fluid is installed in the left quantum spin demonstration box; the right magnetic fluid is installed in the right quantum spin demonstration box; the button is fixed on the booth; and the rocker is fixed on the booth, located below the left quantum spin demonstration box.

[0009] Furthermore, the quantum spin demonstration box on the left and the quantum spin demonstration box on the right are both made of transparent material, circular in the middle, and 8 arrow shapes with the same angles extend outward on the horizontal plane.

[0010] Furthermore, both the left electromagnet group and the right electromagnet group are composed of 8 electromagnets. The 8 electromagnets of the left electromagnet group are respectively located below the 8 arrow-shaped arrows of the left quantum spin demonstration box; the 8 electromagnets of the right electromagnet group are respectively located below the 8 arrow-shaped arrows of the right quantum spin demonstration box, and the 8 electromagnets in the left electromagnet group and the 8 electromagnets in the right electromagnet group are connected in series in pairs at symmetrical positions on the center line of the booth.

[0011] Furthermore, the joystick can be pushed in eight directions, and each pushing direction corresponds to controlling the power supply of the electromagnets in the same direction among the eight electromagnets in the left electromagnet group.

[0012] Compared with the prior art, a demonstration device for displaying quantum entanglement state is provided, in which the positions of the quantum spin demonstration boxes and the electromagnet groups on the left and right sides are completely symmetrical with respect to the center line of the booth, and the arrow shape of the quantum spin demonstration box indicates the direction of quantum spin. The electromagnet below the arrow is energized to make the magnetic fluid in the quantum spin demonstration box flow to the arrow to indicate the direction of quantum spin at this time. When the button is pressed, the quantum distribution demonstration light strip indicates that the quantum on both sides are in an entangled state at this time. Pushing the joystick controls the electromagnet corresponding to the push rod position in the left electromagnetic group to be energized, and at the same time, the electromagnet on the right electromagnetic group is energized. The electromagnets in the iron group that are symmetrical to the electromagnet on the left and the center line of the booth are energized, and the magnetic fluids on both sides flow to the arrows on the quantum spin demonstration box above the position of the energized electromagnets. Push the joystick to control the energization of different electromagnets. The positions of the magnetic fluids on both sides are always symmetrical about the center line of the booth, so as to demonstrate the principle and phenomenon that two quantum particles in a quantum entangled state always have opposite spin directions, and intuitively display the profound and mysterious knowledge of quantum mechanics. At the same time, the form it adopts is full of interactivity and fun, which broadens the channels for popularizing and understanding the relevant knowledge of quantum mechanics.
