The new way to communicate using light.

"Propagation of light pulses with intermodal dispersion in multimode fibers, MMF. Words are mapped to different frequencies (different colors), the optical pulses are stretched into different temporal dispersion curves. This allows for the identification of the pulse frequencies at the receiver, thereby enabling the reconstruction of the input words. Credit: Gao, Z., Jiang, T., Zhang, M. et al."

There are many ways to make light-based communication systems. Normally, we think that the light flashes mean 0 and 1 in a laser communication system. But the 0 and 1 can be two different wavelengths. That means the flash of red can mean 1, and the flash of green can mean 0. This is a useful tool for binary data transmission. But there is one way to transmit data by using light that we don't usually mention. 

In that version, a single wavelength means a single word. The system must only give serial numbers for light- or radiation flashes. Then the receiver can put those flashes back into a certain order. That means red can mean "if", green can mean "and" etc. Researchers can also use radio waves in the same way as lasers. And the point of the CCD camera those people can put a radio spectral scanner. 

There are approximately 600000 words in English. Some people might think to use that kind of data transmission, the system requires 600000 wavelengths. The system can send those messages by blinking the colored lasers in the order that gives words to the receiver. If one color carries one word that makes the system immune to disturbance. 

"Experimental system. a, encoding: Each word is mapped to an optical frequency according to the encoding table. b, Schematic of the experimental setup. c, decoding: Recognize each dispersion curve as the corresponding frequency using the fingerprint dictionary, and then reconstruct the words based on the encoding table. d, implement sentiment analysis using a deep learning model.

The problem is that. Language advances all the time. And the system requires very advanced and complicated transmitter-receiver pairs. But theoretically is possible to create a CCD camera that pixels can separate 600,000 frequencies. And, a transmitter can also have the ability to send 60000 separated frequencies. 

And that means the system must have flexibility. If the system uses the English alphabet. It needs only 52 frequencies for the letters. There are 26 capital and 26 lower cases. And other frequencies for numbers and special marks like brackets. Or the sender can use the words to send numbers. But that creates limitations in massages. 

The system can use red as "A" and the light flashes can involve data which place the certain letter takes in the words. That thing is hard to jam. 

So it's immune for the outcoming errors. But otherwise, it's easy to break. 

The system can also encode lots of words in one wavelength. There can be hundreds of words encrypted in certain colors. The system must only send the serial number of the word that the system sends. This kind of system is more complicated to break. That thing makes this thing more vulnerable to disturbance.

The laptop broke the "post-quantum" cryptography scheme that was meant to protect information against quantum computers.

The fact is that quantum computers are a new thing. Those new and powerful systems are making the regular, binary cryptography old-fashion. Traditional RSA cryptography is very easy to break by using quantum computers. 

So there it needed a new algorithm that can protect networks against quantum computers. This is why NIST (National Institute of Standards and Technology) published the race, to create next-generation cryptography. The advances in quantum computing are huge. And that means those systems are turning more common. 

So maybe quite soon the first quantum servers are in use in private corporations. And sooner than we think, the first quantum-PC:s are sold in supermarkets. That means we must create new algorithms and methods for protecting our networks against quantum hackers. 

There is a problem that nobody knows what will be the next step in quantum technology. And there are many protocols and cryptographic systems tested against the attacks of quantum computers. But some of those algorithms involve mistakes. And one of them is broken by using laptop computers. That thing tells that even the symmetrical curve cryptography and other symmetrical methods don't stand against quantum computers. An algorithm is useless against quantum computers if the laptops can break it. 

The reason why quantum cryptography is hard to break is that the data travels in the form of a qubit. Because the qubit is the particle the attempt to steal information will cause the quantum states of that qubit to be disturbed. And that thing uncovers the attempt to steal information. 

Normally qubits are traveling in the protective laser ray. And that thing makes quantum cryptography more secure than we even think.

There is, of course, a possibility, that quantum systems can be hacked. But the time that the binary computer uses for that thing is extremely long. So if we want to break the code that is made in a second by using a quantum computer, by using a binary computer that takes over a month. This means real-time hacking the quantum systems by using binary computers is impossible. 

So if somebody wants to hack things like battlefield missiles that are using quantum cryptography in their messages by using binary computers, that will take so long time, that this kind of hacking doesn't affect the situation.

If we think that a qubit is like a house, or tower with multiple layers or states we can make quantum cryptography even more secure than it was before. In the case where qubit has let's say eleven states. We can use as an example states 5, 7, and 10 for sending information. So we must not use those quantum states successively. 

If we use only states 5,7 and 10. We might fill other states by using white noise. Or we can send things like images in those states. In that case, if somebody tries to open the message that thing will disturb other states and cause distortion in those images. That means we can see if somebody tried to steal information from the qubits.

The Bird Is Gone

The Bird Is Gone

Could there be an encrypted message where is letters T.B.I.G (The Big) (Terminating Big) and could that mean some kind of demolition device?

What does this message mean? When we are thinking about this message it has been found on the tree, what is in one of the farthest and most isolated islands in the world. Sometimes I have thought is some carrier pigeon left to home for sending a message, and then something happened to that bird. At first, we might think, that somebody was mistakenly released some carrier pigeon, but there is another explanation. 

Is that the very well encrypted message? But is the message some kind of encrypted thing, where are the hidden word "The BIG", if we would take only the first letters of the words. So is there some special bag or something else? Those letters are T.B.I.G, what might mean that there has been happened something big. or T.B.I.G might mean (T) BIG, what might mean "Terminating Big". And is that "terminating big" some kind of demolition equipment. 

Or was there some dead bird laying on the rock. And then someday the persons, who have left that message suddenly have seen that "The Bird is Gone", so there is one little bit more interesting explanation for that message, and could that some ship, what name was "The Bird" was gone. Or did somebody accidentally released some kind of bird as an example carrier pigeon?

Is this "Bird Is Gone" message the key to the mystery of treasury, what is claimed to hide on that island? And how the maker of that message hoped, that somebody will find it?

Above this text is a message, that somebody has sent to a tree on the Cocos island, and that message could be the key to the treasury mystery, what has been told about that island. In that island is claimed to be the treasury, but nobody has been officially found it. When we want to solve some problems, we must think about what is the simplest possible reasons for that thing. When we are looking at things, what we might think as clear, we might find another meaning for the things, what seems regular. So when we are looking like the stories of the lost treasure, we must ask, why somebody wants to hide that thing? If some pirate would hire treasury to the beach a long way from home, how that person would think to return and get the treasury? 

Does that pirate rent a ship, and then go to get that thing from the sunny island? But if the treasury is gold and diamonds, why that pirate would not melt gold, and claim to find jewelry, and sell them to some store? So what that treasury could be? Are they some kind of documents, what is proving about some kind of cooperation with some investors and pirates, and this kind of thing might cause that the pirate could buy himself free from the prison if that person would someday catch because somebody has become suspicious of the origin of the money of the old sea captain.
