In an effort to expand its capabilities in the rapidly expanding quantum computer industry, the Centre is gearing up to launch its long-awaited Rs 8,000 crore Quantum Mission, said Professor Ajay Kumar Sood, the government's principal scientific adviser.
"Quantum technology is capable of providing secure communications in every department, whether it is telecommunications, electronics, space, or defense. The science behind it is extraordinary. Two years ago, we discussed this topic. Multiple ministries are working on it, and it's anticipated to be launched very soon," said one of the government's top scientists.
Department of Science and Technology will lead the National Mission on Quantum Technologies & Applications (NM-QTA) with a budget of Rs 8,000 crore for five years. National security, quantum computing, quantum chemistry, quantum communication, new materials, quantum sensors, and quantum cryptography will all be explored in the mission.

2. What is Quantum Computing?
The term "quantum computing" refers to a system that computes outputs using quantum physics, hence the term "quantum". The smallest discrete unit of any physical attribute, known as a quantum, exists in physics. In most cases, it alludes to the characteristics of atomic or subatomic particles like electrons, neutrinos, and photons.
It is possible to use quantum mechanics' superposition, interference, and entanglement phenomena in certain types of computation, such as quantum computing. Quantum computers are gadgets that carry out calculations in the quantum realm.
Larger realizations of quantum computers are thought to be capable of tackling some computational problems, such as integer factorization, far more quickly than classical computers, despite the fact that they are currently too small to outperform conventional computers for practical purposes. Quantum information science is a branch of the study of quantum computing.
In order to perform calculations, quantum computers use special properties of quantum physics like superposition, entanglement, and quantum interference. Traditional programming approaches are given new concepts in this.

3. Quantum Computers: Why Do We Need Them?
Supercomputers are used by scientists and engineers to solve complex issues. These are enormous classical computers that frequently have tens of thousands of traditional CPU and GPU cores. Even supercomputers, nevertheless, have trouble solving some problems.
If a supercomputer runs into trouble, it's likely that the challenging problem was given to the large classical machine. Complexity is frequently to blame when traditional computers malfunction.
Many different variables that interact in intricate ways make up complex situations. Due to all the different electrons interacting with one another, modelling the behavior of individual atoms within a molecule is a challenging task. In a vast transportation network, figuring out the best paths for a few hundred tankers is also difficult.

4. What is the Basic Unit of Information in Quantum Computing?
In quantum computing, a qubit is the fundamental unit of information. In quantum computing, qubits serve a similar function to bits, but they behave significantly differently. Qubits may store a superposition of all conceivable states, unlike conventional bits, which can only keep a position of 0 or 1.

5. Quantum Computers: How Do They Works?
Compared to supercomputers, quantum computers are elegant devices that use less energy. A quantum hardware system is around the size of a car and consists primarily of cooling devices to maintain the superconducting processor at its extremely low operational temperature.
Bits are used by a traditional processor to carry out its functions. Qubits (CUE-bits) are used by quantum computers to execute multidimensional quantum algorithms. To manipulate the qubit for quantum computing, there are fundamentally three quantum mechanical features. Which are:
Interference:Phase-related phenomena cause interference in quantum states. It is possible to think about quantum interference as wave interference. Similar to a wave interference, when two waves are in phase, their amplitudes add, and when they are out of phase, their amplitudes cancel.
Superposition:A quantum system can be in numerous states or locations at once according to the quantum phenomenon known as superposition. By providing qubits that can simultaneously take on the values of 0 and 1 or both, superposition removes the restriction of computing with the binary system. As a result of the superposition principle of quantum physics, a quantum computer is capable of storing data utilizing a system that can exist in two states simultaneously. Two values of 0,1 can be held in a qubit at once, and four values of 00,01,10,11 can be held in two qubits at once, and so on.
Entanglement:The phenomenon of quantum entanglement is the inability to independently characterize the quantum states of two or more particles that were created together or in close proximity to one another.
No matter how far apart they are physically, entangled qubits interact with one another right away. When compared to a conventional computer, which must read and write from each component of memory independently before using it, this has a significantly greater impact.

6. What are the Uses of Quantum Computing? or Application of Quantum Computing?
There are a number of applications for quantum computing in areas such as:
Artificial Intelligence (AI):The basis of artificial intelligence (AI) is the idea that a computer programme can become intelligent by learning from mistakes and improving accuracy with feedback. Artificial intelligence is ideally suited for quantum computing because this feedback is based on computing the probabilities for various options. Every industry, including the automobile and medical sectors, might be affected.
Molecular Modeling:By replicating the energy of hydrogen molecules, Google has entered the world of complicated chemical reactions. This suggests more effective manufacturing of anything from solar cells to medications and fertilizer.
Optimization: The process of finding the optimum answer to a problem given the restrictions and desired outcome is known as optimization. Critical decisions are made in science and business based on variables like cost, quality, and manufacturing time that may all be optimized. We are able to solve problems that were previously intractable by executing quantum-inspired optimization algorithms on classical computers. This aids in our quest to handle intricate processes like traffic flow, gate assignments for aircraft, package delivery, and energy storage more effectively.
Computational Biology: Quantum computing has been useful in resolving a number of biological issues in the field of computational biology. One of the well-known examples is computational genomics, where the process of sequencing the human genome has been significantly sped up by computer technology. Applications of generic data modelling and storage to computational biology are anticipated given how computational biology makes use of these tools.
Cryptography: The difficulty of factoring huge numbers into primes is a major element in internet security. Such factoring can be done tenfold more quickly on quantum computers than on digital ones. The development of new cryptographic techniques is made possible by quantum computing.
Search: In contrast to traditional algorithms, a quantum algorithm created in 1996 significantly speed up the solution to unstructured data searches.
Generative Chemistry and Digital Drug Design: As effective methods to speed up drug development, deep generative chemistry models are emerging. But there are substantial challenges that, in the future, quantum computers could be able to overcome, such as the enormous size and complexity of the structure space of all potential drug-like compounds. Quantum computers are naturally adept at resolving challenging quantum many-body problems, which makes them useful in applications involving quantum chemistry.
Machine Learning: Some people express hope in the development of quantum algorithms that can accelerate machine learning activities because quantum computers can provide outputs that conventional computers cannot produce effectively and because quantum computation is inherently linear algebraic.
