Quantum security for everybody

Computers are, as usual, advancing in such a fast pace that most of the previous generation could not catch up to understand the thousands of new features exhibited in these binary based systems. Recently, many computer and software engineers are exploring a new system that will soon replace the binary code and revolutionize the computer industry; this system is quantum computing. As we enter the "quantum" age, the data being processed will dramatically change. Rather than having one predefined state of ones and zeroes, data will exist in a billion of different states, allowing computers to examine and transfer data much faster. Not only will this data make computers execute commands more efficiently, but it will also improve data security, since, with data existing in a variety of states, attempting to "crack the code" would almost be impossible. Quantum security does exist today, has been developed for a couple of years, but only exists as an experiment in some of the most advanced physics laboratories. Now, quantum security is currently being developed for everyday people to create quantum "locks" for private and personal data. The Los Alamos National Library has developed a device that generates random numbers and cryptographic keys through random photon polarization based on quantum mechanics. The device uses random polarized filters that causes the photon to exhibit only one state of motion instead of the typical four. Then the physical state of a photon recorded by the filter is then converted into its associated binary notation, With this system, anyone trying to crack the system will affect the stream of protons and the position it is currently in, allowing the system to detect unauthorized decryption immediately. Furthermore, the technology developed is so cheap that anyone can buy it, meaning that one day this technology will be in every computer system in the world for secure data encryption. With this technology, hacking could be a thing of the past, but that does not mean that hacking the information is impossible.
