    Measure Qubits Reality
Click For Summary

Discussion Overview

The discussion revolves around the concept of measuring "reality" in qubits, particularly in the context of solid objects like an apple. Participants explore the relationship between matter, information, and quantum computing, questioning how one might quantify the number of qubits in physical objects.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant questions how to measure the number of qubits in a solid object, suggesting the use of parameters like the number of atoms.
  • Another participant argues that due to quantum entanglement and decoherence, it is difficult to determine the entangled state of atoms in a physical object like an apple.
  • A participant inquires whether it is possible to roughly calculate the number of qubits in a solid object.
  • One response suggests that while theoretically possible, practically counting qubits in matter is extremely challenging due to the vast number of atoms and particles involved.
  • A later reply humorously notes the impracticality of creating an extensive Excel sheet to account for the qubits, implying the enormity of the task.

Areas of Agreement / Disagreement

Participants express varying degrees of skepticism about the feasibility of measuring qubits in solid objects. There is no consensus on whether it is possible to calculate the number of qubits, with some suggesting it is nearly impossible while others entertain the idea theoretically.

Contextual Notes

The discussion highlights limitations related to the measurement of quantum states, including the effects of decoherence and the challenges of isolating particles for measurement.

How can we measure the "reality" in quBits?

Hello
All matter is based in information, and quantum computing use quBits, so I was wondering how can we measure the reaility in quBits?
A certain solid objet, let's imagine an apple, it has a weight and we can calculate (approximately) the number of atoms in it.
How can we know the number of quBits in that apple?
I was thinking about this long time ago, and if could it be possible to develop an excell with the appropriate formulas in which introducing some parameters (for example the number of atoms present in a solid object?) could we find the qubits in it.
Any ideas?

Well I think you need to read up on quantum entanglement , and quantum physics basically, wikipedia will do for starters.
Your question is not so clear it is hard to derive a idea from it but talking about an apple or any other physical object , you can't actually tell the entanglement in it's atoms , when atoms and elementary particles are all together in an object they are usually so much and they are constantly interacting with one another and that causes decoherence so you wouldn't be able to tell.
That's why physicists use extremely low temperatures and magnetic fields and other things to separate individual electrons for example so that would not be able to interact atleast for a while so that they could see and use the quantum entanglement effects.The moment you take away those special conditions the electrons interact and the entanglement is lost.

ofcourse in an apple there could be many particles in an entangled state at the same moment but that happens so fast and they are so many that there would be no way to tell.
 


So would it be impossible to calculate in a rough way (approximate) the number of qubits present in a solid object?
 


In theory almoust anything can be done in reality I think it would be like counting the hair on your head.
Pretty hard close to impossible ofcourse if your not a bold head.

Even in a tiny piece of matter there are millions of millions of atoms and way more elementary particles.So well...
Remember that for one to know if two particles have been or are entangled they have to measure them which requires to separate them from the rest and so on.That's a tough thing to accomplish.
