#23 - Quantum Interrogation: counterfactual measurement and its implications for human thought
Вставка
- Опубліковано 8 сер 2024
- In episode 23 of the Quantum Consciousness series, Justin Riddle discusses quantum interrogation, the observation that in certain scenarios a quantum system can access the result of a measurement without actually making that measurement. This counterfactual measurement is best exemplified in the Elitzur-Vaidman bomb test, in which a bomb is determined to be real or a dud by sending a superposition at the bomb that shifts the probability distribution (or wave function) of a quantum system. The principle of counterfactual measurement applies to quantum computation: could you get the results of a quantum computation without actually running it? And to quantum cryptography: could you get someone’s password without actually changing the information stream? Finally, we wrap up the episode discussing the implications of counterfactual measurement to the human experience. If we accept the premise that each person is themselves a quantum computer, then could you simulate a possible future behavior and get the results of that simulation without actually performing the behavior? This episode definitely goes off the deep end, so hang in there until the end of the episode!

I appreciated the graphics. Some like me are visual learners. It helps make the presentation a stand alone one. Being able to go to specific topics knowing they can be watched independently is valuable for researching particular facets of your theories. I continue to find the speech communication skills fabulous. You don't use notes. Your teaching experience comes through as you move forward through the new information on this topic while bolstering each episode by refererring to previous information in a previoius episode which ties into this new topic. This demonstrates where this theory falls and why it is important. I admire your work and opportunity to learn totally new systems of thinking.
Thank you sincerely for your words of encouragement!
@Infinite Shoeblack That is great! It is important to use a learned resource to assist especially with the medical profession. There are valuable take aways to this series. Be well.
very clear. best explanation ever of quantum bomb experiment
Thanks!
Hi Justin. Again you have layered a scientific explanation that I can overlay onto my direct experience. In 2019 I received what I now think of as quantum information 'from the future' which suggested that if I took a certain action a certain undesirable result would occur. 4 years on I see a number of other unrelated people who did take that action experiencing the exact undesirable result.
There is therefore a high probability (although not a guarantee) that if I had been yet another person to take that action I too would be experiencing the undesired result.
The spooky part is that when I was considering the action I did not perceive that such a negative consequence could possibly result from it. I couldn't see how causal action A could or would ever lead to effect B. That is until I received it as a sudden dump of quantum information into my mind one day.
It was a bit of a paradigm shattering experience because I then had to fundamentally re-evaluate my actions, actions that I was previously convinced were going to lead to a desirable outcome.
pretty sure the last five minutes is a quantum commercial for Nathan Fielder's The Rehearsal
Brilliant. Even if I get lost in the weeds, he brings it home in a succinct way by the end. The point arrives. He's an educator without peer. A synthesizer without equal. No wonder the class is relatively small. Diamonds are relatively small. And brilliant.
Whooooooooooosh !! Right over my head !! I've hit my fractal limit
Just a friendly recommendation! Throughout all of your videos I've had a fantastic time following along, very effective. This one however was a bit difficult because of so many distinct references to locations and flip flops of directions and had movements. Might I suggest using something like OBS to do a screen recording of you interacting with your diagrams on a slide or what have you in real time as you talk about it? You can even super impose it on the video capture you're doing of yourself in realtime. Might be helpful, might even be less editing in post, too! Thanks again for your work as always :)
I audited your class back in 2017 when you were teaching it at Berkeley. It was so fun! I’m still friends with Joe and we have random quantum consciousness discussions every once in a while
Wonderful! Yes those were some good times teaching that class. Joe and I are still in contact as well! Keep up the discussions :)
I've watched all your videos and this is the most difficult one to fully understand IMO.
It would have been great to hear more examples of implications, no matter how outlandish, to help with understanding. It feels like you were holding back to avoid sounding crazy. A sad but understandable concern.
This video is awesome.
23:27 Could you kindly share a link for that zeno booster application? I'm not a scholar, but throughout my genuine interest towards quantum mechanics it does stand out. A way to circumvent the collapse of wave function would be a breakthrough in my understanding, so I presume zeno booster is not doing that? I struggle finding any paper on it.
I was good until you started dropping f-bombs and then I lost it... lol. Happy accidents.
Haha yeah I cut out the bit where I start cracking up after saying it the first time
Congrats on having a remarkably mature audience! I expected the comments to be all about the choice of bombs! Loving this series, and having an unexpected laugh was quite refreshing!
I feel like writing is one of those Zeno boosters, as long as you decide to take the same action as the protagonist with a certain probability(strong measurement).
Counter counter counter counter ... counter quantum Hacker. Reminds me of an episode of Rick and Morty.
Haha it does right?
Hope the Zeno boosters will end COVID all together!
How do you assume it to be possible that the ‘bomb’ can distinguish absorbing a photon and exploding with reflecting the photon and being a dud? I.e., you have assumed it is impossible for the ‘bomb’ to absorb the photon and be a dud, and likewise reflect the photon and be live. This is the ridiculous result of idealized systems not pertinent to reality.
Cant use an imaginary probability. Modulus squared allows us to work with imaginary amplitudes transformed into real probabilities.
A negative probability is real and can be used. It is the probability of x not happening. I think u mix up imaginary number plane with negative probability here. Good work tho
...hahaha...oh boy...so how come did you got to think on hypotheticals, you tossed a coin or did they have a "cause" for your reasoning?
Counterfactual computing does not grant you any free will!
