Does the locality of physical uniqueness allow death and decay?

[pittsburghjoe]

How about Entropy?

 

[The IbanezerScrooge]

locality of physical uniqueness

Please define this phrase.

 

[pittsburghjoe]

A particle in superposition is not very unique or physical.

 

[SelfSim]

I'm gonna presume this thread to be linked with this recent article:
Scientists Are Testing a Mind-Blowing Time Theory in a Nuclear Reactor:

Instead, Vaccaro believes entropy might result from time, not the other way around.

.. if so, then the upcoming reactor testing will throw some more light on the question.

Something needs to be decoherent to have entropy. To have cyclical time ..to age.

All of the concepts of decoherence, entropy and cyclical, imply time. All three require a human mind, which can't make any sense without the concept of time.

Time is what a human mind brings with it, wherever an observation of anything is made by it.
Time doesn't have to be a 'something' which exists independently from a perceiving mind.

 

[The IbanezerScrooge]

A bit over my head, but I've always thought of the arrow of time as our perception of increasing entropy.

I think you'll find it is. QM is a physical theory, and the quantum 'No Cloning' theorem means it must be unique.

Having entropy and ageing are not the same. Ageing implies an increase in entropy. It is possible to define the entropy of an isolated quantum system and its eigenstates.

Are you saying a closed system is not local?

 

[pittsburghjoe]

I think you'll find it is. QM is a physical theory, and the quantum 'No Cloning' theorem means it must be unique.

It is saying the opposite ..non-local waves are not even real, how are you going to clone something that isn't physical?

 

[FrumiousBandersnatch]

If the waves are not real, what is?

Are you really saying particles are non-physical?

 

[pittsburghjoe]

You can't have a closed system without there being an infinite coherent system first.

Particles are real ..decoherent.

Waves are future possibilities of something becoming real.

 

[pittsburghjoe]

All quantum effects require waves.

 

[FrumiousBandersnatch]

Particles are real ..decoherent.

But not real before decoherence?

Waves are future possibilities of something becoming real.

That's one interpretation... so what is the 'something' before it becomes real? What is it that decoheres?

How do you define 'real' in this context?

 

[pittsburghjoe]

Wave-Particle Duality is not usually at the same moment in time.
The 'something' is quantum information. An interference pattern can only happen if all possible paths are virtually taken.
Information isn't lost to the environment, it is used to build a physical particle ..decoherence.

Real is something that has a single possible path.

So quantum information isn't real, but is used to build real particles?

 

[pittsburghjoe]

Information can't be destroyed. It is coherent but becomes local when used in a real particle.

 

[FrumiousBandersnatch]

Information can't be destroyed. It is coherent but becomes local when used in a real particle.

That's not what I asked... let me put it another way, does quantum information have a physical representation (other than a particle)?

 

[pittsburghjoe]

Why would it? You can't destroy something that isn't physical.
