Why anyone on this list might give a crap about QM
by Anonymous 03 Jan '03

03 Jan '03

Here's why wavefunction collapse matters, or might. A few months ago, we were debating the "End of the Golden age of crypto", and that went into a discussion of the inherent (or not!) difficulty wrt factoring large numbers consisting of big primes. And the question that was raised (and is still on the table), is whether 1) is it possible that one day factoring will be 'cracked' and become much easier, 2) whether factoring will always remain dificult, or 3) will we be able to prove 2 above or will we have to live with the uncertainty forever? Quantum Cryptography is a possibility that could allow 'us' (ie, whoever will have access to it) to 'know' for sure that our transmission is secure, based on physical law. This security only exists, however, if we believe current quantum mechanical theory, which says that... 1) Wavefunction collapse happens at measurement time 2) There are no hidden variables 3) ANY attempt to read what the photon states 'really' are will collapse the wavefunction 4) An eavesdropper of a Quantum-encrypted code must necessarily reveal their presence, due tpo the fundamental QM laws of the universe.(4 logically follows from 1,2 and 3 above.) In other words, the use of Quantum Cryptography is an attempt to eliminate the uncertainty associated with difficult (but classical) cryptosystems. But it only eliminates the uncertainty if we believe reality really works this way. TD (#1 and #2)

Re: QM, EPR, A/B
by Tyler Durden 03 Jan '03

03 Jan '03

Actually, Tyler Durden (ie, me) wrote what is attributed to the generic anonymous name of Norman Nescio. Anyway,... >Part of the problem is that the detection equipment is many fermions >looking at single particles. I think QM is easier to understand when >looking at an ion trap. There are lots of photons around for every atom >but the interactions are with fields and the detection is of single >photons (again with massive amounts of equipment, but the atoms don't >interact directly as in EPR or double slit). With all due respect, Pooey Dr Mike. Take a nice, straightforward EPR using two correlated photons produced by KDP-downconversion. How do you exaplain the EPR experiements where pairs of photons are created via KDP downconversion? The two particles are separated at birth and travel through different paths through the apparatus. (And this apparatus can be made aribtrarily large.) If the apparatus does not permit us to determine the path of any single photon, the two photons will have completely coupled measureables (eg, polarization) at the output. The moment will are able to determine the path of ONE of the photons, then the measureable of the other becomes completely de-correlated from the other. This is true on the single photon level, and looked at up close its pretty startling. Now the odd thing (if this isn't odd already), is that we can (and have) perform the change from isolatable to nonisolatable AFTER THE PHOTONS HAVE ENTERED THE APPARATUS. (This was suggested by Wheeler and done around '94 as I remember). In a sense, then, the photons are 'aware' of events happening (relatively speaking) backwards in time. And this is not theoretical. It was predicted via quantum theory and seen in the lab many times. Now obviously we could step back and say that "QM is a useful computational tool. Let's not worry about reality", but that's an intellectual dodge. Classical physics grew up around the desire to understand natural reality, and this "new" fad of ignoring what QM says about reality only arose as a way to move QM forward in the early days. Look, it's not like we say "Don't think of light as an electromagnetic wave. E-M theory is merely a useful computational tool". Likewise just because we are in the odd situation of not knowing what QM says about the universe doesn't mean its not saying anything, or that what its saying is of no interest. With EPR (and, arguably, A-b), we are confronted with obvious "proof" that these particles communicate in ways that are completely different from the models developed prior to 1910 or so. (One of the few intelligent thoughts I've had on the subject is that the particles are still a single quantum object prior to measurement.) With respect to Cypherpunks and cryptography, then, we would be intellectually hypocritical if we thought there was anything inherently more secure about quantum cryptography. But we (I mean, pretty much every working physicist in the world) DO believe this, because this is really the way reality "works". Wavefunction collapse actually "objectively" (if that's the right word in the quantum world) happens and there's no undoing it. It's a basic physical property of the universe. With respect to many worlds, David Deutch, et al have argued that for any single path taken by a particle in a quantum there are innumerable "shadow photons" in the other universes that communicate with the observed photon. We also see just one possible but the complete collection of shadow photons take all possible outcomes. Now while I don't really buy this explanation, I DO buy Deutch's desire to find a picture of the underlying reality (we once spoke on this issue and wildly agreed). I could go on but I've got work to do. No one's actually read this far anyway, have they? -Tyler Durden > >QM is a nice model that works. It is a good mathematical description of >observed phenomena. What else do we need? The idea that a photon >"passes thru" one slit or the other is just a model.

The hologram trick is very interesting; could cause a lot of problems for the adversary. Now the question remains, how to make a hologram within the resources of a common person, to make the system suitable for wide use, not only for a handful of high-tech geeks with closets full of cutting-edge gears. Also, how to make sure the image got properly exposed, so it couldn't happen that a mistake of the sender couldn't result in a false alarm. (Maybe to develop part (half, stripe...) of the image and then check under the red light, before using?) The issue starts to look more complicated than it seemed on the first glance. We have a resourceful adversary, who will quickly learn the tricks. We need a low-tech technology that will be highly resistant against undetected tampering by the adversary. Does anyone know if this wasn't already being solved during the Wars, or the Cold War? I am pretty sure many embassies had problems with adversaries going through their diplomatic mail.
