Quantum Internet and Cyber Security
Author: David Laurent Guffroy
Quantum computing has the potential to revolutionize the way that we use computers and the internet. Unlike traditional binary computing, in which bits must take the form of either a 0 or a 1, in quantum computing it is possible for Q-bits, as they are called, to take intermediate forms. A Q-bit can be both 0 and 1 at the same time. This increases the range of possibilities and enables quantum computing to be far more powerful than conventional computing.

The speed at which a computer can work is largely dependent on its transistors. A quantum transistor can increase the speed of a computer since it is able to work significantly faster than a conventional transistor. Quantum transistors have been created using the concepts of quantum physics that enable particles to communicate across space without actually touching. In the quantum transistor, one beam of light is used to control the properties of another beam of light. This means that information can be communicated far more rapidly than with a conventional transistor. Information can be transferred without the need for any substance to actually travel the distance. The development of quantum computing will depend upon the discovery of methods of harnessing the power of quantum entanglement or of developing superconductors.
The development of quantum computing and the quantum internet has some important implications for cyber security. Rather than simply reacting to threats and problems once they have already arisen, the quantum internet may enable us to take a much more proactive approach to cyber security.
This is because the quantum internet will enable us to tackle security at the level of bits, which is not an approach that is possible with conventional computing. Currently, a bit must either resister a 0 or a 1, but in quantum computing, it is possible for bits to register both 0 and 1 simultaneously. When a quantum bit assumes its value, it is impossible for the bit to be copied without the sender becoming aware of it. This is because copying the bit would cause its state to change. Any threat to security would therefore be detected immediately, at the bit level. Internet users would always know when their security or privacy had been threatened, which would make surreptitious attacks impossible.
Quantum technology is currently being developed that will help bring this form of protection into reality for consumers in the near future. Quantum computing could be contributing to improved cyber security for everyone within the next 20 years.
