# What is Quantum Computing |How does it work and its Future uses?

Quantum Computing is a technology of computer science that focused on the development of technologies which is based on the principle of quantum theory.

Quantum computing is a type of computing that uses the principles of quantum mechanics to process information. In classical computing, the information is processed in binary digits (bits) that are either a 0 or a 1. However, in quantum computing, the information is processed using quantum bits (qubits) that can be in multiple states at the same time.

## What are Qubits?

Quantum bits, or qubits, are the basic unit of information in quantum computing. Sort of like a traditional binary bit in traditional computing. Qubits use superposition to be in multiple states at one time. Binary bits can only represent 0 or 1. However, Qubits can be 0 or 1, as well as any part of 0 and 1 in a superposition of both states.

## What is Superposition?

Superposition is a fundamental concept in quantum computing that describes the ability of quantum bits (qubits) to exist in multiple states simultaneously. In classical computing, a bit can only exist in one of two states, either 0 or 1. However, a qubit can exist in a superposition of both states, with a probability distribution that determines the likelihood of each state being observed.

This means that, unlike classical bits which can only represent a single state at a time, qubits can represent multiple states at once. This property of superposition is what gives quantum computers the potential to perform certain calculations exponentially faster than classical computers, as they can explore multiple solutions to a problem simultaneously.

The concept of superposition can be visualized using the famous example of Schrödinger’s cat, which is a thought experiment that illustrates the idea of a quantum object being in a superposition of states. In this example, a cat is placed in a closed box with a vial of poison that will be released if a radioactive atom decays. According to quantum mechanics, the radioactive atom can exist in a superposition of both decayed and non-decayed states until it is observed, at which point it collapses into a single state. As a result, until the box is opened and the cat is observed, it exists in a superposition of both alive and dead states.

Another important concept in quantum computing is Entanglement, which is a phenomenon where two or more qubits become linked in such a way that their states are dependent on each other. This allows quantum computers to perform certain types of calculations much faster than traditional computers.

## What is Entanglement?

Quantum particles are able to correspond measurements with one another, and when they are engaged in this state, it’s called entanglement. During entanglement, measurements from one qubit can be used to reach conclusions about other units. Entanglement helps quantum computers solve big problems and calculate bigger stores of data and information.

## What is the use of Quantum Computing?

It allows quantum computers to perform certain types of calculations much faster than classical computing, especially when dealing with a large amount of data. For example, quantum computers can factor a large number much faster than a classical computer which is very important for encryption.
Quantum computing is a rapidly growing technology that can harness the laws of quantum mechanics to solve complex problems that are difficult to solve for classical computers.

## How Quantum Computing useful for optimization problems?

It can perform operations on a combination of all possible solutions. It divides the intractable complexity into bits to calculate simple solutions.

## How could quantum computing benefit the financial services industry?

Quantum computers are expected to be able to break many of the encryption algorithms currently used to protect financial transactions. It could lead to the development of new, quantum-resistant encryption methods, which would help to ensure the security of online financial transactions.

## What is the benefit of interference in quantum computing?

It will allow for the encryption of data within large databases. The main advantage of quantum computing is the ability to handle complex problem-solving. By harnessing the quantum property of superposition, qubits can exist in an infinite yet contained number of states: 0, 1, or any combination of the two.

## Which technology is making quantum computing easier to access and adopt?

It uses the qubit technology as the basic unit of information rather than the conventional bit. The main characteristic of this alternative system is that it permits the coherent superposition of 1 and 0, the digits of the binary system around which all computing revolves.

## Which technology will quantum computing impact most significantly?

It will impact Artificial Intelligence most significantly. Quantum computing could have massive impacts on the tech industry and the world. One of the Biggest impacts will be in the world of cybersecurity.

## How will quantum computing affect artificial intelligence (AI) applications?

Today’s artificial intelligence (AI) systems are only as good as the data they’re trained on. The AI industry is currently taking the advantage of large datasets to train AI models and make them more useful. However, as these datasets will become limited, researchers are exploring other ways to improve AI algorithms. One such way is a quantum computer. It is a new frontier of computer science that will help in finding better AI algorithms in a short period of time because of its most powerful technology.

## How does quantum computing works?

A classical processor uses bits to perform its operations. A quantum computer uses qubits to run multidimensional quantum algorithms. Quantum computing takes advantage of how quantum matter work, whereas classical computing uses binary bits 1s and 0s. However, quantum computing uses 1s, 0s, and a1 and a0 simultaneously.

A quantum computer uses qubits to run multidimensional “quantum algorithms”, “quantum simulation”, etc. Their processing power increases exponentially as qubits are added.

Quantum computers process information in a fundamentally different way than classical computers. Traditional computers operate on binary bits while quantum computers transmit information via qubits. The qubit’s ability to remain in superposition is the heart of the quantum’s potential for exponentially greater computational power.

Quantum computers utilize a variety of algorithms to conduct measurements and observations. These algorithms are input by a user, the computer then creates a multidimensional space where patterns and individual data points are housed. For example, if a user wants to solve a protein folding problem to discover the least amount of energy to use, the quantum computer would measure the combinations of folds; this combination is the answer to the problem.

## Why Quantum Computing is Important?

Quantum computers may have the potential to uproot some of our current systems. The cryptosystem known as RSA (Rivest-Shamir-Adelman) provides the safety structure for a host of privacy and communication protocols, from email to internet retail transactions. Current standards rely on the fact that no one has the computing power to test every possible way to de-scramble your data once encrypted, but a mature quantum computer could try every option within a matter of hours.

## Future of quantum computing?

Quantum computing is a rapidly evolving field & it’s still in its early stages. However, it has the potential to revolutionize many areas of science and technology, including cryptography, drug discovery, machine learning, and artificial intelligence.
