Neutrino-Powered Financial Trading In Our Future? 275

An anonymous reader writes "In a new feature on the future of high-frequency trading, Wired suggests that neutrino-powered financial trading systems may be coming soon, which would enable extremely low-latency information to be transmitted directly through the center of the Earth between major financial exchanges. If finance becomes the killer app for neutrino communication technology, it may ultimately make Neutrino SETI feasible. Quoting: 'It is only a matter of time, perhaps a few decades, says Alexander Wissner-Gross, a Harvard physicist, before some hedge fund decides it needs a particle accelerator to generate neutrinos, and then everyone will want one. Yes, they travel slower than light, but they indisputably can tunnel through the earth, cutting thousands of miles off an intercontinental message. And just a few days before the Battle of the Quants, right before the bad news about faster-than-light neutrinos, researchers announced they had sent a message by neutrino from the Fermilab accelerator in Chicago to a detector a kilometer away. According to Dan Stancil of North Carolina State University, the signal traveled at "very close to" the speed of light. Unfortunately, the data rate was only about 0.1 bits per second, meaning it would be useless for much more than sending a yes/no signal. "With the right modulation scheme, this could be increased by at least one or two orders of magnitude," Stancil said, adding "I don’t know of a compelling commercial application." But we’ve all heard the (apocryphal) story that Thomas J. Watson of IBM predicted "a world market for maybe five computers."'"

      Hong Kong to US is about 150ms latency using conventional technology verizon [verizonbusiness.com]. So taking your own example of needing 100 bits to transmit a useful message (I don't know if that is realistic), the message would need to be transmitted faster than 666bps just to break even with existing communications. Given the cost of neutrino detectors and the current state of technology it just doesn't seem likely.
      • by hakey ( 1227664 )
        I forgot the latency through the earth which is about 42ms. So actually you would need to transmit at 100b / (150ms - 42ms) = 952bps just to break even.

        It's usually buy, sell or hold, but really you want a specific number, which could be very detailed if you're doing microtransactions. And you probably need a few bits to identify which stock you're selling, and all this needs a carrier of some sort. The expensive part, though, is probably securing the transmission.

      That's true.

      But by travelling straight through the earth instead of being bounced around it from satellite to satellite, the total distance is perhaps only a hundredth as far, and so the information can be thus relayed proportionally faster.

      It's worse than depressing. There is no socially redeeming value to high frequency trading. At best the practice steals a small amount of value from any affected fundamental (or non high speed technical for that matter...) trade. At worst, it may have caused the flash crash or be able to trigger a similar event.

      If we as a world collectively had reasonable securities laws, the idea of high frequency trading would soon become moot. For the right to host the capital markets, the exchanges should be required to be neutral to latency, and certainly not co-host high frequency trading with the exchange computer systems. Also, a very small Pigovian tax on financial transactions would clean up a lot of undesirable activity in the securities markets, this included, while being a source of revenue proximate to provision of a societal good (that being regulation for efficiency sake of the capital markets).

    Clearly this is why the financial industry is in such a constant state of crisis. They are basically dumb, believing what any says, as long it might make then a buck. The more stupid, outlandish, and gibberish compliant the idea is, the more they like it.

    I mean really, if they wanted near zero latency communication, they should just come to me for some basic technology. For instance, a basic, yet expensive, path is telepaths. Right now we would simple takes twins or triplets or whatever, test them for basic ability, and then train them. Pay each 100K a year to be on staff for a few year, then replace then as needed. This would be a great job for someone right out of high school. For the longer term we would go to some country with low regulation and genetically engineer the telepaths. At first this would be just selective breeding and early training, but eventually we should have labs set up to create telepaths on demand. Pay for their room and board, keep them on for 10 years, then send them on their way with a couple million in trust.

    A more expensive and lower bandwidth method would be quantum entanglement. Chang the spin on one particle, it's entangled particle will immediately be changed as well. A 8 bit system could be built, An alternating all up then all down could be sent as a metronome, then an STX, then a certain amount of datadata, then and ETX, then a check sequence, then an EOT. Speed would be limited on by how long one must hold a state for reading. The advantage here is that there is absolutely not latency.

    You see, there are always simple solutions when one thinks about it.

    • Lol. For a moment, I thought you were serious.
      I don't see why quantum entanglement would be more expensive and lower bandwidth though. This could be done with simple, mass produced consumer electronics/optics. Too bad it doesn't allow actual information transfer.

You do so to buy or sell something you want or need. As long as you get what you want for the price that you want, it doesn't matter what middle men or DoS gamers are on your market.

  • It fails to state just how not good we are at detecting neutrinos. If all the matter across the interior of the planet doesn't stop/defelct the neutrino, some little foot long antenna or something isn't going to either. They're not nearly that easily detectable. Let's see...what do I know of that we have right now that already solves this problem? Oh yeah, entangled particles.

    I think there's more mileage to be had from gravity-based communication systems. For example, take the "Mach Lorentz Thruster". It's basically a capacitor that is oscillated back and forth very rapidly with synchronized cycles of charging and discharging.

    The original reason for it was to generate a net thrust by charging the capacity pushing it in one direction, discharging it, and then pushing it back again. This generates a net force since a charged capacitor by relativity has slightly more mass than a discharged capacitor.

    One side effect though is that if you already have a gravity signal of the appropriate frequency, then such an oscillating system can pick up that signal. In other words, the MLT can produce a gravity based signal and pick up a gravity based signal. All in theory, of course. But at least it's progressed to the point where one can generate detectable levels of thrust with it. One could probably generate the gravity signal merely by vibrating a massive weight at the right frequency.

    Now one such MLT acts so I understand a lot like a dipole antenna. I think it should be possible to make a large phased array of these things and have an ability to detect gravity signals of a tuned frequency, more or less what would be wanted for communication. And it should have better gain by a very large amount (like pretty much everything else does) than a corresponding antenna for neutrinos.
    • hmm, yes mass and energy are same thing, but that c squared factor means you don't get much gravity per Joule. How much energy have you got in one of those capacitors, yes the electricity moves fast, at the 1/3 c. But if you want a gravity of detectable quantities, i think you'd be better off wiggling a massive object quickly.

    With the right modulation scheme, this could be increased by at least one or two orders of magnitude

    Sure. If anyone ever figures out how to modulate a neutrino beam. Now we're having problems already just detecting them.
    I suppose it would be theoretically possible to modulate the accelerator beams, but with the energies involved, I suspect that will be quite a challenge too.
    And then there is the small matter of latency. The neutrino beam may be fast, but the whole process of converting the information stream in a modulated beam, and then analyzing the data at the detectors to find the few neutrinos that didn't come from the sun, will take probably more time than sending the data through fiber optics would.

    • Actually, that's easy, and has been done: http://arxiv.org/abs/1203.2847 [arxiv.org]

      (Full disclosure: I'm an author on that paper)

      Modulation (strictly speaking) isn't required. To make the system work, you only need semi-reliable one-bit fast communication, and slow communication otherwise. On the slow channel:
      "I'll be ready to send a neutrino pulse at 12:00:00.000000"
      "Send me a neutrino bunch at 12:00:00.000000 if it would be profitable to buy "
      Then the beamline simply pulses or doesn't-pulse the beam at that time, de

OTOH it may take neutrino-based networking for market makers to do this ;)
