Quantum Entanglement and The No-Communication Theorem

Quantum entanglement is a physical phenomenon that occurs when pairs or groups of particles are generated, interact, or share spatial proximity in ways such that the quantum state of each particle cannot be described independently of the state of the others, even when the particles are separated by a large distance.

the no-communication theorem or no-signaling principle is a no-go theorem from quantum information theory which states that, during measurement of an entangled quantum state, it is not possible for one observer, by making a measurement of a subsystem of the total state, to communicate information to another observer. The theorem is important because, in quantum mechanics, quantum entanglement is an effect by which certain widely separated events can be correlated in ways that suggest the possibility of instantaneous communication.

Hey guys, I have a pretty awesome announcement: I have officially joined Twitter!


If I had more than 2000 subs at this point, then I could make a common community post, but apparently YouTube doesn't allow that, so I'm gonna be posting and pinning this comment everywhere.

I've been posting to this channel a lot less lately, but I find it awesome that a pretty large number of people are watching and commenting on these videos - so here's to reaching (at this time) 275 subs! Really nice, huh?

Since a lot of people seem to really love this channel, I'd like to say just one thing to our small but growing community: I'm working on a ton of new stuff right now, including cool new video styles and something which will (hopefully) turn out to be awesome.

Above all, thank you guys for watching!

why does this only have 300 views, it's awesome and well explained, thank you and keep it up

Amazing video! Seriously, like PBS Digital Studios good.

Well thought and planned video! Also please continue the series of navier stokes equations and calculus!

Hey i loved the video and



There is 100% chance you will the breakthrough challenge.

Flipping your state doesn't even flip the other person's state when they are entangled. If you have two quantum coins in a superposiiton of HH and TT, if you flip the second one before measuring it then you change the correlation to HT and TH. It is a common misconception that if you flip the second one then you've change it to TT and HH, which is not what happens. It's not different in this sense than having two real coins in an envelope where you flip yours upsidedown before opening it.

If we were to set up an Instance Distant Communication experiment where the communication is being made through particles that has been separated in superposition and now are being used in two sets of the double slit experiment synchronized by atomic clocks to communicate and for verification an ordinary laser beam between earth and the moon, we should be able to send information faster than light and get it verified about 1.2 seconds later by the sender.

Two modern computers running artificial intelligence should be able to play and finish a Tic Tac Toe, Chess and AlphaGo game in under 1.2 seconds finishing the games before local causality allows them to have begun.

All communication between the computers making up their game move strategy that ultimately will cause one of them to win or end up in a draw will arrive for verification using the laser beam about a second later.

This setup should be able to send Instance Distant Communication verifications of its outcome and all information that previously has been sent between the computers before the laser beam has been able to send its real-time information of that the games even has begun.

Would this work?
If not, then experiments like the Delayed Choice Quantum Eraser are flawed for assuming that a superposition of two entangled particles would mean that if one of them are in particle of waveform would affect its partner.


I guess that it's something I don't understand in quantum mechanics that must make this a flaw method because it seems a little bit too easy and I would appreciate a little bit of help getting my head around where I go wrong.

Also, what program do you use for animating all that stuff?

How does person B observe if his photon has collapsed without the act of collapsing it?

could you do a video about states of matter. like.. all of them, 22 or something.
