looking at a quantum system changes the behavior you observe

a quantum system is in a superposition of states

Yeah, and they lowered the laser enough so it only shot out one photon as a particle

but once you get into things like quantum eraser

you will realize its absolutely not as simple as observing just collapsing the wavefunction

They've done experiments with no physical interaction that proves the observer plays a role, but they don't tell ppl cuz it would upset the atheist applecard

lol no

Quantum Eraser again?

It's an elimination?

It is technically a measurement interaction that that brings the wave into the particle?

like chalk being in the presence of the beam?

High Orbit discussions

quantum eraser is where you observe the path in the double slit experiment, but you later on precisely destroy that information in a quantum way so it cannot leak back into the environment

if you do that, you recover the interference pattern as if you had never observed it

Conscious knowledge of the system is the key not a physical measurement per se

I am never unblocking dashi again. can we ban this guy already?

That makes me think of Penrose's "amnesia" theory

The convo needs some scenery

so, its not that observing causes collapse, its that if your current state has a memory of interacting with a quantum system, you cant interact with a superposition of it that would contradict that previous measurement

he's harmless

unless you delete all traces of the measurement

I need to read this for myself.

Hm

This is hard to believe. I think I no longer can believe realism.

Yes Rhythm this is why I said QM is upstream of philosophy for me

@fuguer so could you say the idea of infinite dimensions is the same as the idea of infinite memory patterns?

I am going to take it step by step of the text book I got for now, Fuguer. Thanks though, but I am going to take it slowly.

retrieval in qm is pretty interesante

Li Chengfeng from the quantum information laboratory of the Chinese Academy of Sciences developed a solid-state quantum memory and demonstrated the photon computing function using time and frequency.
