    Decoherence
In summary, the conversation discusses whether a marble ball can be considered a subsystem of an entangled system. The answer is that the marble ball is composed of atoms that are entangled with each other and the environment, and the randomness of their entanglement can be controlled to some extent. However, the question of whether the marble ball can be teleported macroscopically remains unanswered due to the impossibility of predicting the behavior of quantum entanglement.

Can a marble ball be considered as a subsystem of an entangled system where it is entangled with the environment? Or is "subsystem" in entanglement/docoherence only reserved for small quantum thing like electrons or photons?

I have learned that the answer is the marble ball is composed of zillions of atoms and they have separate entanglement with one another and the environment. And the randomness is like that of Brownian motion so we can move the marble ball in one average position. But I have a question.. and a harder one so it's more challenging for you.

You can control Brownian motion by pressure or volume of the container. In the marble ball.. supposed you can influence the entanglement of each atoms and unrandomize the random entanglement to give positions.. can you make the marble ball vanish and teleport macroscopically?

You are asking what the laws of physics say would happen in a situation in which the laws of physics don't apply. There's no sensible answer to that question, so this thread is closed.
 

1. What is a marble ball subsystem in quantum decoherence?

A marble ball subsystem in quantum decoherence refers to a small object, such as a marble ball, that is used to study the process of quantum decoherence. This process involves the loss of coherence or interference between quantum states, leading to a classical behavior of the system.

2. How is a marble ball subsystem used in quantum decoherence experiments?

In experiments, a marble ball subsystem is typically used as a model system to study the effects of decoherence on larger quantum systems. The marble ball is prepared in a superposition state and then allowed to interact with its surrounding environment, causing it to lose its coherence and behave classically.

3. What factors can affect the decoherence of a marble ball subsystem?

The decoherence of a marble ball subsystem can be influenced by various factors, such as the temperature, interactions with the surrounding environment, and the measurement process. These factors can cause the subsystem to lose its coherence and exhibit classical behavior.

4. How does studying marble ball subsystems in quantum decoherence contribute to our understanding of quantum mechanics?

By studying marble ball subsystems in quantum decoherence, we can gain insights into the fundamental principles of quantum mechanics, such as the process of decoherence and its effects on larger systems. This research also has practical applications in fields such as quantum computing and quantum information processing.

5. What are some potential future developments in the study of marble ball subsystems in quantum decoherence?

Some potential future developments in this field include improving our understanding of the mechanisms of decoherence, finding ways to mitigate its effects, and exploring the potential applications of decoherence in quantum technologies. Researchers are also investigating the role of entanglement and other quantum phenomena in the decoherence process.
