Quantum sensors have applications in a wide variety of fields including microscopy, positioning systems, communication technology, electric and magnetic field sensors.
One of these are the perfectly common motion sensor that detects if you move your phone, which is based on quantum phenomenon, like the phase shift between photons send in different directions.
First link: “But your smartphone is not a quantum computer, yet”
The title was a question. The answer the article you linked gave was “it doesn’t use quantum.”
The second link was describing regular effects as having quantum origins. Which is everything! Everything everywhere has a basis in quantum mechanics.
"Radio waves are photons, and their behavior is described by quantum electrodynamics. "
Yes, underpinning the entire universe is quantum mechanics. The light from a campfire is photons. No one would write an article saying, “Cavemen used a sophisticated quantum light source.”
Your claim was that smartphone motion sensors were quantum. You linked to Wikipedia about quantum sensors which did not say anything about phone sensors.
Apple and all phone manufacturers say they use mems motion sensors.
First link: “But your smartphone is not a quantum computer, yet”
I never claimed that it was, quantum computers are still experimental.
Sorry I didn’t care to read the rest, because you started off with such nonsense.
This is also in the text:
Also, your smartphone contains a digital camera with a CCD-sensor. This sensor is based on the photoelectric effect – which was explained by Albert Einstein by introducing quanta of light,
Okay, now you’re literally just chewing words to become meaningless.
On this basis, every fucking piece of technology is quantum technology because guess what, the ENTIRE UNIVERSE WE FUCKING LIVE IN is adherent to quantum physics and mechanics, and anything, any technology, any kind of energy transference, can be broken down to some kind of quantum phenomena which would be either directly or indirectly used. A simple steam engine can be quantum. Your bedroom lights - regardless if you use LED, incandescent, neon, or a fucking candle.
The very definition of a quantum sensor is that it utilises a quantum effect DIRECTLY, instead of relying on a transitive property that we measure in a different way. A CCD sensor might rely on “a quanta of light” therefore making it “quantum technology”, but it won’t be a quantum sensor.
All the Newtonian mechanics can be described as a much more precise quantum function.
But this is precisely the difference I’ve been talking about regarding what can be considered a quantum sensor.
Observing a Newtonian system maketh not a quantum sensor - even though, again, all the observations are the result of quantum functions and quantum phenomena. To utilise the previous light example, this is akin to facing away from a light and using the shadows it casts to estimate the properties of the light. Whereas a true quantum sensor would be akin to measuring the light’s properties directly, instead of the transitional properties of the aforementioned shadows.
Furthermore, in no scientific debate will you ever qualify by a flurry of ad hominems followed by telling your opponent to “piss off”. That is the strategy of a sore loser who cares not about facts but about being right (even when being wrong) above all else. And that, my friend, goes against science in general.
If the device doesn’t use quantum effects directly, it isn’t a quantum sensor.
Otherwise words have no meaning and textbooks would call 1860’s steam engines electric quantum engines because materials are held together with electric effects and atoms have quantum properties.
Well everything uses quantum effects directly at least the highs field like you said. Your definition is therefore bad. But the examples do use gravitons because they measure gravity the same a camera uses photons to measure light, which are both quants and are measured in “easy” ways.
Just because you are posh about it and try to define it as only the large hardron collider
Do you mean the Soli radar? That ended up in what, 2-3 phone models altogether?
Most phones do not have motion sensors.
No literally a common motion sensor.

None of the current phone IMUs utilise quantum phenomena for measurement. They’re MEMS/FOG/RLG systems.
Quantum IMUs are the size that requires rack mounting.
OK but still the GPS using timing based on an atomic clock in space is absolutely sophisticated, and that is in even the cheapest smartphones today.
Your claim was quantum phenomena utilisation in phone sensors.
Let’s stop moving the goalposts please.
I’m just tiring of the negativity here, so this is my last response in this thread.

You were wrong. Get over yourself.
And read the links you provide as proof.

Yet you linked the article that made that statement and then refuted it!
Quote from the article you linked:
https://qt.eu/applications/how-your-smartphone-uses-quantum-mechanics
Where it gives an example of how your phone uses quantum mechanics.
Yes a photon. Light is photons. The light from a caveman fire is photons. I already explained that.
Can you really not see that you are wrong? Or is it THAT hard to say “ah damn, got that wrong”?

You are annoying and uninformed, by far the most of the universe as we perceive it as human beings is Newtonian.
Now piss off with your ignorant crap.
The only ignorant one here is you, buddy.

I mean everything electric is a quantum sensor not to defend anything
edit: further g sensors and accelerometers implemented by piezoelectricity are quantum sensors. They just use materials that make the sensing easy
