    Decoherence
In summary, the conversation discusses the concept of decoherence and its impact on our perception. It is mentioned that in psychology, perception is believed to occur within a 0.1 second time frame, but there is a need for a physical explanation. However, the decoherence times for larger objects, such as a cat, are much shorter than this. The question is raised as to why we do not perceive this decoherence. It is then stated that decoherence times for everything we can see are below the nanosecond timescale and our brain is too slow to distinguish between different results without complete decoherence.

Yeah, the beta movement from pshycology for example, it impose that a perceptions matter in a 0,1 s (+ or -), but this need a physical explanation. The decoherence times for examle cat alive cat dead is very low than this. But we are there while decoherence. Why we don´t perceive it. The decoherence time for position in macroscopic objects is very long for perception times like physcology. But it is long for Planck time. Why is the reason we don´t perceive the system while decoherence??

Decoherence times for everything you can see are below the timescale of nanoseconds. If the object is more than 30cm away from you, not even the light from the object can reach you in that time. Your brain is at least 1 million times slower.

Anyway, the timescale is not so important here: Your eye (or any other organ) cannot distinguish between ("measure") different results without having a complete decoherence between those different results.
 

Related to Why don't we perceive systems during decoherence?

1. Why is it difficult to perceive systems during decoherence?

Decoherence is a process in which a system becomes entangled with its surrounding environment, causing the system to lose its quantum properties and behave classically. This makes it difficult for us to perceive the system as a whole because it is now interacting with its environment and no longer exists in a pure quantum state.

2. What happens to a quantum system during decoherence?

During decoherence, a quantum system loses its coherence and becomes entangled with its environment. This results in the system behaving classically and losing its quantum properties, making it difficult for us to perceive it as a whole.

3. Can we ever perceive systems during decoherence?

It is possible to perceive systems during decoherence, but it requires advanced technology and techniques. For example, quantum computers are able to manipulate and control quantum systems, allowing us to observe and measure them during decoherence.

4. How does decoherence affect our understanding of quantum mechanics?

Decoherence plays a significant role in our understanding of quantum mechanics. It helps explain how and why quantum systems behave classically, and how they interact with their environment. It also has implications for quantum computing, as it is essential for preserving the coherence of qubits.

5. Is decoherence a reversible process?

Decoherence is considered to be an irreversible process. Once a system becomes entangled with its environment, it is difficult to reverse the process and restore its quantum properties. This is why it is crucial to minimize decoherence in quantum systems, especially in applications such as quantum computing.
