What a world without decoherence would be like

[marcus]

Here are the Pirsa video talks by Robin Blume-Kohout:
http://pirsa.org/index.php?p=speaker&name=Robin_Blume-Kohout

I've just seen one talk, that he gave October 1, just a couple of weeks back.
The topic is Quantum Knowledge.
http://pirsa.org/09100089/

What is it. What is quantum data compression. What is a quantum agent.
How can you tell something is a quantum agent.

Robin B-K is good. I have to recommend this talk to just about anybody, at any level, who is interested in the quantum-classical borderline of reality.

Thanks Marcus, I just tried to give it a 5 min skim and I partially like what I see. I need to get time to listen to this talk in it's entitry.

I connect particularly to some things he says, for example his behaviouralism suggesting that the action of a system reflects it's knowledge. This is really close to how I envision that you can infere the microstructure of the environment or any other system by observing and restructuring the information. Also the idea that quantum agents (I would call it a quantum inference system) would outperform in certain situations a classical agents also makes excellent sense to me. I see the parallells to game theory where it's been noted several times that quantum games are in a certain way "more efficient", I think of them as beeing "more fit", which is why there is a selection for them in the evolutionary view I have.
But I think the spirit of intent is very similar.

I'll try to read this more properly tonight maybe.

He does a great job of explaining what a world without decoherence would be like, and how the concept of quantum knowledge helps us understand this hypothetical world.

First, let's define what decoherence is. It is the process by which quantum systems lose their coherence and behave more classically. In other words, it is the mechanism that causes the weird and counterintuitive behavior of quantum systems to disappear and for them to start behaving in a more predictable and understandable manner. Without decoherence, the world would be a very strange place indeed.

In his talk, Blume-Kohout explains how a world without decoherence would be like a "quantum zoo," where all sorts of bizarre quantum phenomena would be on display. For example, particles could be in multiple places at once, objects could be entangled with each other instantaneously, and measurements would not have definite outcomes. It would be a world of pure quantum weirdness.

But how does the concept of quantum knowledge help us understand this world? Blume-Kohout introduces the idea of quantum data compression, which is the process of taking a large amount of quantum information and condensing it into a smaller amount of classical information. This allows us to make sense of the quantum world by reducing the amount of information that we need to process.

He also introduces the concept of a quantum agent, which is an entity that can manipulate and control quantum systems. In a world without decoherence, quantum agents would be able to harness the full power of quantum mechanics and perform tasks that are impossible in our classical world.

So how can we tell if something is a quantum agent? Blume-Kohout suggests that we look for certain characteristics, such as the ability to manipulate and control quantum systems, the ability to perform quantum measurements, and the ability to store and transmit quantum information.

In conclusion, a world without decoherence would be a strange and fascinating place, full of quantum phenomena and possibilities. And by understanding the concept of quantum knowledge and the role of quantum agents, we can start to grasp the potential of this hypothetical world and the mysteries of quantum mechanics.
