The combination of physics and electronics is what constitutes quantum computation. But what is the need of quantum computers when we have supercomputers? Is it even possible to create one?
Calculations which are beyond human reach are effortlessly done either through classic computers or supercomputers. But the need for more advancement can lead to the development of quantum computers. China, one of the most technologically advanced countries did launch the world’s first quantum-communication satellite, thus breaking all the boundaries in advancement. Through this major breakthrough, China has successfully created an unbeatable benchmark for its contenders.
Micius, the quantum satellite, which is backed with encryption technology, can create a future with hack-proof communications. Secure communication is becoming a dream, with cyber threats having its powerful leverage over it. Even though more countermeasures are being taken, there will be parallel loopholes to break that effort. But not anymore, once the quantum computations are adopted, data authentication will be a breeze.
Quantum for Communication
How do you avoid your data from being hacked? Is it even possible to transmit the encoded data to a long distance without any breach? Photons are the best answer for this. Quantum which deals with the behavior of energy in atomic and sub-atomic levels is the core reason for this breakthrough. If a data is transferred through photons, then the possibility of the data being hacked is zero. Apart from this, scientists can also conduct numerous virtual experiments which may not be supported even in supercomputers.
Classical Computing Vs Quantum Computing
Computations in classical computers are dependent on Boolean algebra that is logic 0 and logic 1. Usually operable with 7-mode logic gate principle, classic computers are ensuring a better performance but with certain limits. Circuits are getting smaller and faster by the day, but it is also to be noted that there is a certain level of threshold beyond which they cannot perform. In simple words, circuits are made from a large number of capacitors and resistors, of which the switching limits to different logic levels is dependent on overall speed and physical limits.
On the other hand, a Quantum computation surpasses all the limits encountered in classical computations. Capability to work with a two-mode logic gate and a mode of Q01, Quantum computation, can modify 0 as the superimposition of 0 or 1. However, this action is not possible through a conventional classic computation. There is nothing as beyond the reach in quantum theory due to the principle of superimposition and entanglement. The amalgamation of these two principles provides a greater computation power which is actually beyond the reach.
Final thoughts
Quantum computing is a classic technology with a modern approach. Quantum is having a major influence across all the sectors. From DNA modeling to transmitting or processing highly complex data systems, Quantum computations can reach leaps and bounds. With the capability to outperform the speed of supercomputers, Quantum computation will surely create a new robust era for the whole mankind.
