Future Benefits of Quantum Computers
1. Cryptography and Peter Shor’s Algorithm
In 1994 Peter Shor (Bell Laboratories) found out the first quantum algorithm that, in principle, can perform an efficient factorization. This became a complex application that only a quantum computer could do. Factoring is one of the most important problems in cryptography. For instance, the security of RSA (electronic banking security system) – public key cryptography – depends on factoring and it is a big problem. Because of many useful features of quantum computer, scientists put more efforts to build it. However, breaking any kind of current encryption that takes almost centuries on existing computers, may just take a few years on quantum computer.
2. Artificial Intelligence
It has been mentioned that quantum computers will be much faster and consequently will perform a large amount of operations in a very short period of time. On the other side, increasing the speed of operation will help computers to learn faster even using the one of the simplest methods – mistake bound model for learning.
3. Other Benefits
High performance will allow us in development of complex compression algorithms, voice and image recognition, molecular simulations, true randomness and quantum communication. Randomness is important in simulations. Molecular simulations are important for developing simulation applications for chemistry and biology. With the help of quantum communication both receiver and sender are alerted when an eavesdropper tries to catch the signal. Quantum bits also allow more information to be communicated per bit. Quantum computers make communication more secure.
