Undergrad Measuring electron spin and measuring entangled electron spin
So you mean, for a single superposition state (), this can be anything because we can alter probabilities (c1 and c2 complex numbers) with observing at different angles. But for entangled state this is initially determined () and this is a unique state therefore we can only measure the outcomes...- Athraxin

Undergrad Measuring electron spin and measuring entangled electron spin
So you say measuring doesn't alter the state for entangled state and we get %50 spin up and down. Thanks for your answer sir.- Athraxin

Undergrad Measuring electron spin and measuring entangled electron spin
Suppose, we have a stern-gerlach setup, we are going to measure only one silver atom, (it is entangled with another silver atom but that partner is not in this setup we have only one of the entangled atoms in this setup), our magnetic measurer has shifted 60 degree from vertical axis by us. What...- Athraxin

Undergrad Measuring electron spin and measuring entangled electron spin
Hi people, Lets assume, we have a stern gerlach setup and we are going to measure an atom's last orbit electron's spin with 60 degree from vertical axis. Therefore, in this case, our outcomes would be 3/4 for spin up, 1/4 for spin down. Let's assume, we have the same setup but we are going to...- Athraxin

Undergrad Delayed Choice Quantum Eraser with altered beam splitter
I thought the similar process I guess. I thought that if we use that (20:80) beam splitter it will change possibilities of photons in one detector, for example in this case R01: will %80 photons from upper slit %20 photons from lower slit, R02: %80 photons from lower slit, %20 photons from upper...- Athraxin

I'm right? That usually doesn't happen. :) Thank you btw.- Athraxin

Undergrad Delayed Choice Quantum Eraser with altered beam splitter
But I've removed them from the setup as you see in the picture. How can I see them even they are absent in this setup?- Athraxin

Undergrad Delayed Choice Quantum Eraser with altered beam splitter
So for instance we will see a pattern %80 photon of all on R01 and %20 photon of all on R02 also they will show same (destructive&constructive) patterns. In this case, one of them will be more crowded with photon counts, other one will be less crowded with photon counts. Thanks for you answer sir.- Athraxin

Undergrad Delayed Choice Quantum Eraser with altered beam splitter
Hi People, In Kim's real setup for interference patterns we use a beam splitter as 50:50 (reflectance,transmittance rate), lets assume we use 20:80 (%20 reflectance, %80 transmittance) for beam splitter what could we observe in this situtation on detectors (except D3,D4)? Dont forget we use...- Athraxin

Undergrad Delayed choice quantum eraser setup with no beam splitter
I suppose I got it now. It seems like we splitting photons in the real experiment but in reality we actually get random entangled photons from slits without knowing other random entangled photons coming after them (in phase or out of phase). That's why we can't get an interference pattern...- Athraxin

Undergrad Delayed choice quantum eraser setup with no beam splitter
I agree with you sir, I think published results must be more accurate to rely on. Anyway I wanna thank you for your answers. But I'm still not able to comprehend why they are coming from uncorrelated sources, there is only one source for pump photons in the experiment, after splitting pump...- Athraxin

Undergrad Delayed choice quantum eraser setup with no beam splitter
Thanks for sharing this result with me sir. However, Dr. Jeffrey H. Boyd has said the opposite in his youtube video. - this link must redirects you to the exact time of the video. He says we will see an interference pattern. Right now, I'm really confused. I believe you are right sir but at...- Athraxin
