  • 1.  Measuring Both Entangled Particles Simultaneously

    Posted 04/23/24 09:53 AM

    Hello!

    I could not find a "Quantum" group to ask this. 

    This question has been bugging me and I cannot find any answers. Even Claude 3 was stumped. 

    Hypothetical Question: 

    "Can an individual in an entangled or simulated entagled state, measure both entangled particles at once? 

    Please do not focus on the "how?". I feel that would be missing the point. Imagine we are 100 years into the future and have the technology to do this experiment. Would we be able to measure both entangled particles?

    Respectfully,

    Julian

    Hi Julien,

    I'd say, where is the issue at all? The question is your expectation of the outcome!

    First we have to talk about measuring "at the same instant". How would you make sure, it is the same instant for the entangled particles? Or is it the same instant for you?

    Both particles are regular particles. You can measure a feature of the particle. Entanglement just talks about the relationship between the particles and your measurement will reveal the information of both sides instantly. It will lead to a random experiment in the end. And it was one in the beginning too, independent of making the measurement at the same time.

    That's just my understanding how this entanglement works.

    Cheers

    Roland

    Reading this thread back 6 months months later has certainly shown me how little i knew and still don't know. Always curious though!

    I'll ask 100 silly questions until just 1 makes sense and the dots connect. 

    Thank you for your well written response!

    In quantum world, dots connect and disconnect at the same time and therefore things make sense and do not make sense at the same time !?!  ;-)

    Ditto on the some of the deets with Roland. Entanglement is more like an energetic relationship. A good way to imagine this through an allegory would be through hugging someone with a very strong perfume.

    While you may be separated from that person at a great distance, some of that scent will remain on you. Mirroring to a degree with the energy signature. The signature scent will be relatable to the event and host who gave you it. It matches the host event, but will change due to variance. How energy transforms and blends into the environment. 

    Also; it depends on "what" you're trying to measure. Measuring becomes different with particles in motion. For instance, some will notice that "Virtual Particles" kind of blip in and out of existence, while some pairs of "Virtual Particles" cancel each other out.

    Hope this helps. Good topic by the way and a good week

    Dear Julian

    >>>> Can an individual in an entangled or simulated entagled state, measure both entangled particles at once?  <<<<

    Having read a few popular science books on Quantum Physics, I have some points to make:

    • I assume you refer to "individual" as a person which is a "macroscopic" object. This means your question is pointless because that individual cannot enter quantum entanglement state.  
    • Another well know quantum phenomenon is about quantum decoherence which causes the "observed" quantum state of particles to collapse which means the measurement can be meaningless if it can de done at all.    I recently watched a documentary on quantum computer and one point about its security is that the data communicated between 2 quantum computers cannot be tapped like what can be done with traditional computers because the tapped data will "decohere" and no data can be stolen, again if it can be done at all.  
    • Even if the measurement can be possible by whatever reason, Heisenberg's principle of uncertainty causes the measurement to be incomplete and therefore useless in one way or another.
