Quantum computing has the potential to revolutionize the way we use computers and the Internet. Unlike traditional binary computing, in which bits must take the form of a 0 or 1, in quantum computing it is possible for Q-bits, as they are called, to take intermediate forms. A Q bit can be 0 and 1 at the same time. This increases the range of possibilities and allows quantum computing to be much more powerful than conventional computing.
The speed at which a computer can run depends largely on its transistors. A quantum transistor can increase the speed of a computer as it can work significantly faster than a conventional transistor. Quantum transistors have been created using concepts from quantum physics that allow particles to communicate through space without actually touching each other. In the quantum transistor, one light beam is used to control the properties of another light beam. This means that information can be communicated much faster than with a conventional transistor. Information can be transferred without the need for any substance to travel the distance. The development of quantum computing will depend on the discovery of methods to harness the power of quantum entanglement or the development of superconductors.
The development of quantum computing and the quantum Internet has some important implications for cybersecurity. Instead of simply reacting to threats and problems once they have arisen, the quantum internet can allow us to take a much more proactive approach to cybersecurity.
This is because the quantum internet will allow us to address security at the bit level, an approach not possible with conventional computing. Currently, a bit must resist either a 0 or a 1, but in quantum computing it is possible for bits to register 0 and 1 simultaneously. When a quantum bit assumes its value, it is impossible to copy the bit without the sender noticing. This is because copying the bit would cause its state to change. Therefore, any security threat would be detected immediately, at the bit level. Internet users would always know when their security or privacy has been compromised, making surreptitious attacks impossible.
Quantum technology is currently being developed that will help make this form of consumer protection a reality in the near future. Quantum computing could be helping improve cybersecurity for everyone in the next 20 years.
