The word “observed” has largely been conflated with human perception in the layperson’s understanding of quantum mechanics. When they were first experimenting with the dual slit experiment, they were simply trying to make measurements to predict where an electron might end up after entering one of the two slits. However they soon discovered that their measurements changed the behavior of the electron. That behavior has been denoted as an observation however observation is very vague.
It’s better to say “a measurement which causes a wave-function collapse” rather than an observation. When phrased that way, it feels a lot more explicit and it allows lay people like myself to ask the next question “what causes a wave function to collapse?”
Source: I just asked my physics PhD wife about this a couple nights ago and she did her best to explain it to me.
If anyone can explain what exactly causes the wave function to collapse, id appreciate it. Because I can’t understand anything I read online.
Also this meme checks out. A person could observe their CPU with the right conditions and instruments to cause a wave function collapse. But I believe a Qbit can reset its state no?
I’m sorry but what you describe pretty much sounds like… observed
If you use your eyes, nothing happens. Most people think “observe” means they can just look at the experiment and expect it to change. That’s why so many people end up in metaphysics thinking their own perception has any impact on the outcomes of physical states. In reality, it makes no difference.
Say you were a spy, and you think there’s a laser guarding the largest diamond in the world.
There’s no way to detect if the laser is there without putting some form of matter in the way of the laser. Be it a hand, or spray bottle.
Now at the museum, a mist won’t set off the alarm, but you’re still reflecting some of the photons out of the beam and into your eyes. Otherwise you wouldn’t see the beam…
But for a quantum experiment, where we care about each individual photon, spraying a fine mist will affect the experiment. Sticking anything in that laser beam path will affect the measurement.
So how do you make a measurement without interacting? As far as we know, you can’t.
That makes perfect sense
“The wave function collapse is just this thing that happens, you know.”

The Schrödinger equation is a multi variable second order partial differential equation. You end up with a “position operator” and a “momentum operator” (momentum is mass times velocity, so we focus on the velocity bit). Because of the way that taking a partial derivative works, you end up applying one you can’t get the other.
Idk that’s probably a terrible explanation (I got a C in that class lol), but it is really cool when you see how the math works.
Perhaps the wave function always collapses no matter what, but the way it collapses changes? If there was no screen for the photons to interact with they’d continue to act like waves but since there’s a screen they collapse at some point on it dictated by the wave. And if you try to observe how they end up there you end up collapsing it earlier so where they go are dictated by the earlier state of the wave.
For a mathless explanation, I believe it’s because in the quantum world all the atoms that interact are part of the same system. That includes the ones that make up the instruments and the scientists themselves. If you put the photons in an experimental apparatus the results can change because the system is different. Meaning you can influence the waveform collapse simply by experimenting to try and understand it.
I hope that’s right I watch a ton of physics YouTube, so I hope I’m absorbing some of this stuff.
For more crazy shit, see how photons traveling across the universe cause the electron they originate from at the start and the electron they terminate at the end to agree to exchange that energy across space and time. It’s mind bending. From the photon perspective (at the speed of light) a journey across the cosmos is instantaneous. No time passes for the photon from its frame of reference.

Wait, what’s the math? At this point that may be way more useful to understand.

Quarked it up again
RIP BOZON
Fucking W
You’re dead now.
I’ve certainly died of cringe. DNR
It’s wild isn’t it??? Someone doing NPC dances on twitch about a viewers deceased grandma??? What a world we live in.
The computer is constantly both bricked and not bricked. No way to know until you push the power button
Quality greentext tbh
um akshually quantum computers have a QPU not a CPU
Would it not still be a Central Processing Unit?
Depending on the design they might still have a CPU, but it wouldn’t be where the quantum wizardry happens.

That’s… not how quantum mechanics work.
That’s… how quantum mechanics works.
That… Might be how quantum mechanics works sometimes.
Until the state of the matter is transmitted in any way or form the matter is in a superposition. This includes getting hit by an electron or a photon.
But it’s how a joke works…
What? You shoot high energy photons off your eyes/ears/nose?
