Quantum Computers are a fact. They are rapidly evolving technologies in the real world. As quantum computing is likely on the verge of emerging, companies, researchers, and even those in power are investing heavily in it.
Medical advances, artificial intelligence, and research in space and quantum computing are likely to lead to breakthroughs that will reach even more markets.
What are Quantum Computers?
Machines that use theories of quantum physics to process are quantum computers. The only values of classical computing are 0 and/or 1. In contrast, quantum computing allows qubit states of 0, 1, or both.
Using qubits, quantum computers are radically more powerful than classical computers.
PRINCIPLES OF QUANTUM COMPUTING
Three of the principles of quantum theory make quantum computing possible:
1. Superposition
A computer bit is logically either 0 or 1.
A qubit can be 0. 1 or both.
For example:
Think of a flipped coin. It is heads or tails or both. It has not settled on the ground and is neither. It is partially in the head/tail state. Quantum computing works analogous to this.
2. Entanglement
Two qubits can be paired. A change in one requires a change in the other, regardless of the distance between the two.
This allows for rapid data processing.
3. Quantum Interference
Quantum systems are capable of augmenting answers that are correct and inhibiting answers that are incorrect. This provides a mechanism for addressing more complex problems.
THE SIGNIFICANCE OF QUANTUM COMPUTING
Classical computing cannot address the breadth and depth of computational problems that quantum computing can. For example, the following are applications that could be achieved:
Medicine
Consider the ability to simulating molecules and chemical reactions to design new treatment for personalized medicine, vaccines, or novel cancer treatment, etc.
AI Applications
Consider the ability to use quantum computing to implement more advanced machine learning, speech recognition, data analysis and robotics, etc.
Cyber security
There is a paradox: quantum computing can be used to break some codes and to create the most secure means of communication.
Futuristic Weather Prediction
Improved climate prediction models and more effective ways to advance disaster prediction would be possible.
Advanced Space Research
Quantum computing could enable more complex simulations, improve navigation in deep space, and optimise satellite use.
How India Is Entering the Quantum Race. India’s development of Quantum Tech is also promising. The Government of India launched the National Quantum Mission, which is concerned with enhancing research infrastructure, building computing capacity and advancing related technologies. Several research institutes and the IITs are working on several aspects of quantum tech, including quantum communication, quantum cryptography, and the development of quantum processors, among others. These developments are going to create new job opportunities in India. With several startups and corporates in India exploring the application of quantum tech in banking, healthcare, agri-tech, and defence, students and technology specialists can expect many opportunities in the near future. Quantum computing is still very nascent. However, the next decade is expected to bring many breakthroughs that will disrupt how we think about and approach scientific and industrial challenges.
