Some basic questions about Quantum Entanglement

In summary: Your name] In summary, the conversation discussed questions and clarifications about quantum entanglement. It was established that it is not possible to directly interact with the entangled particles, but measuring them does constitute a form of interaction. It was also clarified that the particles' attributes do not have a fixed tempo for change, and any changes in their attributes are a result of the entanglement and their interactions with the environment.

Good day All,

I've done a bit of reading on quantum entanglement and it seems that I'm lacking some basic knowledge about quantum physics. So here goes:
(Attribute maybe substituted with state)

1. Is it possible to interact with one of this quantum entangled particles?
Here interact means to force the change of a / the attribute of such a particle. This does not refer to measuring. Two examples: E.g. A. Force the particle's attribute to a fixed state - let's say; down (doesn't matter what the current attribute is). B. Toggle the particle's attribute (if possible without measuring it first)

2. Would measuring said particle constitute some form of interact?
Thus; just the fact that we are measuring it, means that we will change it.

3. Is there a "natural" change in the particles' attribute?
I've read that these particles' attribute changes by it self. (I may be misunderstanding this) Is there a fixed tempo for the change?

That's it for now :)

Hello TX,

Thank you for your questions about quantum entanglement. As a scientist who specializes in quantum physics, I would be happy to provide some answers and clarification on the topic.

1. It is not possible to interact with one of the entangled particles in the way you described. Quantum entanglement refers to a state where two or more particles are intrinsically connected, and any changes to one particle's attribute will instantaneously affect the other particle(s) regardless of the distance between them. However, this does not mean that we can directly manipulate or control the attributes of the particles. The entanglement is a correlation between the particles, not a physical connection that we can manipulate.

2. Measuring the particle does constitute a form of interaction, as it involves a physical process that affects the particle's attribute. However, this does not necessarily mean that we are changing the particle's attribute. Measuring a particle in a quantum entangled state will collapse its wave function, resulting in a definite attribute, but this does not necessarily mean that we have changed the particle's attribute. It is still subject to the laws of quantum mechanics and can change again in the future.

3. The particles' attributes do not have a fixed tempo for change. In a quantum entangled state, the particles' attributes may change in a correlated manner, but this is not a natural or predetermined change. It is a result of the entanglement and the particles' interactions with their environment.

I hope this helps to clarify some of your questions about quantum entanglement. If you have any further questions, please don't hesitate to ask. The field of quantum physics is complex and constantly evolving, so it is always important to continue learning and exploring.


 

1. What is quantum entanglement?

Quantum entanglement is a phenomenon in quantum physics where two or more particles become connected in such a way that the state of one particle is dependent on the state of the other, regardless of the distance between them.

2. How does quantum entanglement work?

Quantum entanglement occurs when two particles are created or interact in a way that their properties become dependent on each other. This means that even if the particles are separated by a large distance, any change in the state of one particle will affect the state of the other particle instantaneously, defying the laws of classical physics.

3. What is the importance of quantum entanglement?

Quantum entanglement is important because it allows for the possibility of secure communication and quantum computing. It also challenges our understanding of the universe and the fundamental laws of physics.

4. How is quantum entanglement measured?

Quantum entanglement is measured by observing the correlation between the states of the entangled particles. This can be done through various experiments, such as the Bell test, which measures the amount of entanglement between two particles.

5. Can quantum entanglement be used for faster-than-light communication?

No, quantum entanglement cannot be used for faster-than-light communication. While changes in the state of one particle do affect the state of the other, this does not allow for the transfer of information faster than the speed of light. Any communication using quantum entanglement would still be limited by the speed of light.
