Quantum Distance? (See me derive it.)

In summary, charge, magnetic flux, conductivity, and distance can all exhibit quantum effects, but they are not necessarily always quantised. Conductivity is noted to be rational, meaning it can be expressed as a fraction of quantised values. However, while resistance can be generated as a quantised value in certain systems, it is not always quantised like charge is. There was also an error in the dimensional analysis provided, as conductivity is expressed as charge^2 time^3/(mass length^2).

As per: https://en.wikipedia.org/wiki/Elementary_charge
Charge is quantum.

As per https://en.wikipedia.org/wiki/Magnetic_flux_quantum
Magnetic flux is quantum.

Magnetic flux is measured as follows:
[itex]Magnetic flux = \frac{Energy * Time}{Charge}[/itex]


Thus:
[itex]\frac{Charge}{Magnetic flux}[/itex] is quantum. (Quantum/Quantum = Quantum)

It has the measurement:
[itex]\frac{Charge}{Magnetic flux} = \frac{Charge ^{2}}{Energy * Time}[/itex]



As per: https://en.wikipedia.org/wiki/Von_Klitzing_constant
Conductivity is quantum.

Conductivity is measured as follows:
[itex]Conductivity = \frac{Charge ^{2}}{Energy * Time * Distance}[/itex]


Taking the top two questions:
[itex]Conductivity = \frac{\frac{Charge}{Magnetic flux}}{Distance}[/itex]

Quantum = Quantum / Distance
Quantum / Quantum = Distance = Quantum

Distance is quantum.

Anybody see anything wrong with this?

Thank you,

"is quantum" does not make sense. I think you mean "is quantised".

Conductivity can show quantum effects, but this does not mean that there are fundamental steps of conductivity.

Indeed this is what I meant.

Instead of there being fundamental steps of conductivity, conductivity is noted to be rational. (You can express it as a fraction of quantised values.)
Can the same be said for distance then, as per what was shown above?

Thank you,

As resistance due to the quantum hall effect, in two-dimensional systems at low temperature and strong magnetic field.

There is a way to generate a quantised resistance, but it does not mean that resistance IS always quantised as charge is.


Oh, and I found an error in your dimensional analysis:

Electric charge: e
Magnetic flux quantum: Φ = h/(2e)
Quantum hall effect constant: e^2/h

No, you don't get a length here. In more basic units, conductivity is charge^2 time^3/(mass length^2).
 

1. What is quantum distance?

Quantum distance is a measure of the distance between quantum states, which are the possible states that a quantum system can be in.

2. How is quantum distance calculated?

Quantum distance is typically calculated using the Hilbert-Schmidt distance formula, which takes into account the inner product of the two quantum states.

3. What is the significance of quantum distance in quantum mechanics?

Quantum distance is important in quantum mechanics because it allows us to measure the difference between two quantum states, which can help us understand the behavior of quantum systems.

4. Can quantum distance be measured experimentally?

Yes, quantum distance can be measured experimentally using techniques such as quantum state tomography or quantum state discrimination.

5. How can quantum distance be used in practical applications?

Quantum distance has many potential applications, such as in quantum computing, quantum cryptography, and quantum information theory.
