Synchronized random bit generator

In summary, the conversation discusses the possibility of constructing two devices that can generate the same random bits indefinitely, even when spatially separated. The conversation also clarifies that this would not violate the speed of light, but would still be considered pseudorandom number generators. The conversation ultimately concludes that it is not possible to have truly random numbers in this scenario.

Is it possible to construct 2 devices which simultaneously generate (the same) random bits indefinitely? No matter how far apart spatially they are. And I don't mean a pseudorandom number generator with the same seed. I mean something like sharing entangled particles, but without the need to exchange stuff continuously.

It wouldn't violate FTL, so what's keeping us from doing it?

Well, by definition, any such devices would be pseudorandom number generators. If the two devices were separated by enough space to no longer be causally connected, for example, then they might as well be operated at different times, too. If they're operated at different times, yet produce the same sequence of numbers, then by definition those numbers are not random.

That's true. Good point.
 

FAQ: Synchronized random bit generator

What is a synchronized random bit generator?

A synchronized random bit generator is a type of computer program or hardware device that produces a sequence of random bits, or binary digits, in a synchronized and controlled manner. This means that the bits are not completely random, but follow a specific pattern that can be reproduced by other synchronized generators.

How does a synchronized random bit generator work?

A synchronized random bit generator uses a combination of mathematical algorithms and external sources of randomness, such as atmospheric noise or radioactive decay, to generate a sequence of random bits. The synchronization aspect ensures that the generated bits are consistent and predictable, while still maintaining a level of randomness.

What are the applications of synchronized random bit generators?

Synchronized random bit generators have a wide range of applications in fields such as cryptography, statistical analysis, and simulation. They are used to generate random numbers for encryption and decryption, as well as for creating unbiased samples in scientific experiments and simulations.

Are synchronized random bit generators truly random?

No, synchronized random bit generators are not truly random. While they may appear random, the bits are actually generated through a predetermined algorithm and external sources of randomness. However, they are considered to be pseudorandom, meaning they are unpredictable and statistically indistinguishable from truly random sources.

How can I ensure the security and reliability of a synchronized random bit generator?

To ensure the security and reliability of a synchronized random bit generator, it is important to use a high-quality algorithm and regularly test and validate the generator's output. It is also recommended to use multiple synchronized generators to increase the level of randomness and reduce the risk of bias or manipulation.
