# What is Quantum Computing? Quantum Computing

Quantum computing is a branch of computer science that deals with the principles of quantum mechanics and its application to computing. It is based on the principles of quantum mechanics, which are algorithms and logical processes that are very different from those used in traditional computers. To explain it simply, it works with data in terms of qubits (quantum bits) instead of bits, like conventional computers. A bit can have a value of either 0 or 1. Presently, almost all computers store information as a series of 0s and 1s as binary digits called bits. A qubit can have a value of either 0 or 1 at the same time. This property is known as ‘superposition’. When superposition is applied to quantum mechanics, we get something called quantum computing — processing information using qubits instead of bits and performing computations using quantum algorithms and gates.

## Why Quantum Computing is important?

It is a processing technology skilled at solving specific problems much more quickly than classical computers. It exploits quantum mechanical phenomena, such as superposition and predicament, to perform operations on data. In particular, they are expected to be useful for tasks associated with complex high-dimensional problems. Quantum computers are different from classical computers because they depend on quantum mechanics to function. These computers are an example of the growing technology that will challenge how we understand and describe the concepts of security and privacy. This computing is a type of computing that uses quantum bits, which are units of quantum information.

The difference between classical computing and quantum computing is the information which is stored and used. The information in this type of computer is stored in the form of qubits, which can be 0, 1, or both 0 and 1 at the same time. This property is called superposition. When superposition is applied to quantum mechanics, we get something called quantum computing — processing information using qubits instead of bits and performing computations using quantum algorithms and gates. Quantum computers are capable of performing a specific type of computation called quantum computation.

It is a set of algorithms, based on the quantum mechanical phenomena of the principle of superposition and tangle, that are designed to take advantage of quantum mechanical effects to speed up certain types of computation. One important application of quantum computers is quantum computation. Quantum computation applies quantum mechanics to solving specific problems to make them more efficient, such as in the search for new breakthroughs in the field of medicine.

### How do Quantum Computers work?

A quantum computer works by exploiting quantum mechanical phenomena such as superposition and entanglement. It was designed in the early 1990s, but the field has advanced rapidly since about the year 2000. Current Quantum Computers are hundreds of times less powerful than quantum computer expected to be built a decade from now. These computers use qubits, which are units of quantum information. A bit has two states, which are 0 and 1. A qubit can be together 0 and 1 at the same time. This is called superposition. When superposition is applied to quantum mechanics, we get something called quantum computing. The processing of information using qubits instead of bits and performing computations on it using quantum algorithms and gates.

#### The difference between a Quantum Computer and a Traditional Computer is:

• The differences between the quantum computer and traditional computers lie in the fundamental principles each computer is built upon.
• Traditional computers use binary bits, which are either 0 or 1, to process information.
• Quantum computers use qubits, which are simultaneously 0 and 1.
• The ability of a quantum computer to be in two states at once is called superposition, which is the principle used to make a quantum computer exponentially more powerful than traditional computers.
• Quantum computers are vastly different from traditional computers. They use quantum bits (qubits), which are simultaneously 0 and 1. This allows them to be exponentially more powerful than traditional computers.
