Potentially a new idea for storing information in time itself and thus a new memory chip.

Or how about this:

Two big mirrors both on earth.

And then let a laser reflect between them.

At the very end they are reflected back slightly different or simply put receiver on other side.

This should increase the path the laser follows, so more length...

Bye, Skybuck.

Hmmm, maybe the universe itself is a very good way of preserving our data somehow.

It takes billions of years for the light to reach us.

We transmit all of our data in light or radio or something into the galaxy.

That way our data keeps travelling for billions of years.

While on earth all hardware devices come and go... but our signals keep travelling.

If we could find a big reflector in space then we could aim the beam at that.

And then some day in the future we could recollect all the information that we sent/shot at it ! ;)

Bye, Skybuck.

What we could do is the following:

1. We can design a spaceship/spacecraft, like voyager

1. and send it into space with it's sole purpose to function as a reflector for us.

2. And then we can use it to keep sending laser beams at it.

1. Then it becomes our way of storing information in the galaxy.

2. The further away it gets the more information we can store.

Hopefully it will then be possible to eventually store years of data.

First 1 year then 10 years then 100 years and then 1000's of years.

That would be cool.

And all we would need for it to recollect data is laser beams and such ;)

Perhaps if the laser beam starts to act weird we might also discover some weird fluctuations in space ! For new theories or something or new discoveries ! ;) :)

Bye, Skybuck.

One potential benefit and problem at the same time is:

1. The laser beam would start to accelerate the spacecraft.

1. The spacecraft might start to move at the speed of light and maybe even fall apart or disintegrate.

2. Perhaps this can be prevented by generating some heat on the other side of the spacecraft so it functions as a counter-force.

If heat is enough to counter/balance a laser beam I don't know this will have to be experimented with or calculated.

Maybe there is another way to produce a counter force to keep it steady ;)

Bye, Skybuck.

it is not a new idea, this was used many decades ago, also with ultrasonic waves in glas or metall wires. It is no random access memory. "

Multiple wires could be used to represent "memory cells".

This way it does become random memory access for the wires ;)

Bye, Skybuck.

Just like progressive scientist would do, insist on types of scientific evidence that are impossible to procure. Declare your idea may be considered real only if others that you purportedly deem will be interested, will have the unique ability to bring the actual evidence you purport to exist, into their laboratories, and will strike them with their mallets, and then analyze their physical properties.

Go ahead and disregard the accomplishments of the purely observational sciences=97astronomy, e.g., which gets along quite comfortably, without bringing real planets, real stars, real galaxies and real black holes into laboratories and having them become struck with their mallets.

Voyagers (and more modern interplanetary probes) use two way ranging (or even three way ranging).

In this system, a well known data sequence is sent towards the probe at an exactly known frequency. The interplanetary probe receives the stream, performs an _exact_ fractional frequency change (say 1/2 or

When the signal is received on Earth, the distance to the probe can be calculated with a fraction of the wavelength (at least in principle). Since the frequency change ratio is exactly known, the doppler shift also gives a very accurate radial speed (regardless of probe local oscillator stability). To get the tangential position and speed, celestial mechanics can be used to reduce the possible solutions.

The frequency change at the probe is required, since if it would transmit the response back on the same frequency, it would block the receiver.

Anyway, this principle would make "active" mirrors on the lunar surface feasible at giga or terabit speeds with somewhat sensible power levels.

This would still need some frequency shifting system on visible wavelengths.

If the receiving and transmitting stations could be installed at wildly separate locations on the Moon, receiving the signal from with one telescope, amplify with erbium amplifiers, transfer it to some location in an other crater with optical fiber and somehow amplify it to kW level and send it back to Earth with an other telescope. Most likely, the sending and receiving stations on Earth would also have to be quite far from each other, possibly on different continents, in order to avoid direct leakage from Tx to Rx.

Hello,

if you store a lot of bits in each wire, it is still sequential access. One bit per wire is useless.

Quite right. Still, although it's not a new idea, right now DRAMs require one transistor (or at least one diode) for every bit, where a reverse-biased diode acts as a capacitor.

Chips like the Intel 1103, of course, also had one circuit cell per bit, because they were shift-register serial memories.

If one could implement something analogous to a delay line on a chip, so that a small number of transistors could regenerate a larger number of bits, then, even if the memory is slower, there would be a potential for a significant increase in memory density.

Better yet would be if it was possible to put something like a Williams tube on a chip. So that somehow a memory cell using a few transistors could have random access to more bits than there were transistors. This was something that core didn't achieve, since while there were few vacuum tubes or transistors interfacing to a core memory, one core was still required for every single bit.

Putting it on a chip, I figure that instead of a 2-D array of bits on the face of a picture tube, only a 1-D array of bits on some surface would be possible.

I don't think there's any technology that makes this practical today, but _in theory_, the ideal memory would be something like a Williams tube - where a large number of bits are selected from by means of deflection voltages, without any need to manufacture one home for each bit. Even by a process as simple as lithography.

What I want to know is...

Can you take a stream of entangled photons and split-route them into two se= parate (very low loss) fiber optic loops, then take one of the loops a mile= away, then change the polarity of one loop and instantaneously detect the = same change in polarization in the distant loop?

That would be cool.

No just the bits in the single wire would be sequential but that's ok.

That's what computers do anyway to ram. They like storing bytes, and groups of bytes.

Thus such a system which stores bits is usuable. If it must be then everything could be load into the computer, manipulated and send back.

So there are possibilities plenty.

So for example the first wire stores a million bits, the second wire stores a million bits, the third wire stores a million bits.

This means the million bits within the wire are indeed sequential, but the wires themselfes could be seeked and would be like random access memory.

Each wire has their own sender and receiver to keep it looping. So each wire is a loop which can be tapped into.

Each wire can be though of as a "seekable memory cell" ;)

Ofcourse the sequential bits can also be manipulated but that would be a more expensive operation...

Then again if the timing is just right... then perhaps even single bits could be manipulated and replaced ;)

Hi,

This 'Quantum Data Buffering' experiment EricP mentioned shows that there is no entanglement connection between the two beams once they have been separated in the "entanglement generation" block, since they disprove the "instantaneous spooky action at a distance" in their experiment by slowing one beam and detecting the quantum states of each beam at different times. Both beams may be exact mirror images of each other, but other than that they have no more connection to each other than any other two beams of light do.

cheers, Jamie

No..that would be like random access to sequential memory. It resembles old phone switching gear, but with bits instead of gossip.

mike

That's a shame.

I'll read EricP's link. I haven't had time to keep up with this sort of thing, lately.

No, it wasn't. The 1103 was a 1K x 1 DRAM. Maybe you're thinking of the 1401?

Oddly enough, Skybuck seems to post his stuff when the moon is full.

Since the charge transfer was not 100 %, some electrons remained in the cell, which were added to the new charge transferred from the previous stage, thus digital regeneration would be required quite frequently, perhaps after 1024 stages. Thus, n x 1024 well organization would make sense as a disk replacement, with relatively short "seek" times and fast data transfers.

Of course, current CCD camera layout are quite similar and capable of storing multiple bits in each well. If the maximum charge for each well is 100000 electron charges and if we could detect the difference of 4 electron charges, the cell could store 14 bits or 16384 different states. For reliable operation, some ECC system across multiple shift registers would be needed, to reduce the quantum effects.

Don't forget I am wrong more than 50% of the time :D
