What Is Quantum Computing?


Quantum computing is an area of study that focuses on the development of computer-based technology focused on the principles of quantum theory. Quantum theory defines the nature and behavior of force and energy in quantum numbers (atomic and subatomic). It uses a combination of bits to perform specific arithmetic operations. Everything works much better than its predecessors. The advent of quantum computers is at the forefront of computer performance, with the huge advantage of operating certain operating cases. For example, quantum computing excels like similar simulations.

Quantum Theory

Now that you have got some brief idea on the topic of what is quantum computing? let’s dig a bit deeper into quantum theory. The development of Quantum theory began in 1900 with the introduction of Max Planck. The presentation made by the German Physical Society, in which Planck introduced the idea that energy and objects exist in individual units. Advancements made by many scientists over the next thirty years led to the modern understanding of quantum theory.

Elements of the Quantum Theory

  • Power consists of distinct units; in contrast to the continuous wave.
  • Particles of energy and matter, depending on the circumstances, may act as particles or waves.
  • The flow of basic particles appeared randomly and, therefore, could not be expected. 
  • Simultaneous measurement of two corresponding values ​​- such as the shape and power of a particle emergence. If one value is measured accurately, the value of another value will be more accurate.

What Is QUBIT?

Quantum computing uses qubit as a basic unit of information and not a standard bit. A key feature of this unique approach is that it allows for parallel opposition to the zero, the binary system digits in which the entire computer is rotated. Bits, on the other hand, can have only one value at a time – either one or zero.

This feature of quantum technology means that qubit can be both zero and 1 at the same time, and in different proportions. This proliferation of states enables a quantum computer with only 30 qubits, for example, to perform 10 billion cable operations per second, which is about 5.8 billion in addition to the most powerful PlayStation video game console on the market.

Differences Between Quantum And Classical Computing

The idea of what is quantum computing? might be clear by now but we also need to understand the major difference between quantum and classical computing. 

Quantum and classical computing are two compatible worlds with similarities and many variations, such as using qubits rather than bits. Let’s look at the three important differences.

Programming Language

The Quantum computer does not have its programming code and requires the development and use of very specific algorithms. However, classical computing has common languages ​​such as Java, SQL, and Python.

Information Delivered

Information can be copied without being disturbed. However, quantum computing cannot be copied or read without being disturbed.


The Eavesdropper can break into communication with high computing power. However, quantum computing provides any interruption of communication that will be detected by communicating parties.

Operating Condition Of A Quantum Computer

These computers are extremely sensitive and require a certain amount of pressure and temperature to install. When these devices come in contact with external particles, measurement errors and deletions of state separation occur, which is why they are closed and must be operated using standard computers.

Quantum computers must be free of atmospheric pressure, temperatures close to zero (-273 ° C), and input from the earth’s magnetic field to prevent atoms from moving, colliding, or interacting with nature. Also, these programs only work for very short periods, so that information is damaged and cannot be stored, making it even more difficult to obtain data.

Main Uses Of Quantum Computing

Apart from knowing what is quantum computing? Let’s just know the main uses of it. Computer security, biomedicine, innovation, and economics, are some of the areas that can be changed with the advent of quantum computing.

Here are some of the benefits:


Companies would optimize to expand their investment positions and improve fraud detection.

Health Care

The industry will benefit from the development of new drugs and genetic therapies, as well as DNA research.


Quantum programs include risks, but also the development of data encryption, such as the new Quantum Key Distribution (QKD) system. This is a new system for sending sensitive information using light signals to detect intruders.

Mobility And Transport

Companies like Airbus use quantum computing to build better aircraft. Qubits will also make significant progress in traffic planning and route development.


Quantum computers can modify computer calculations by creating some sort of unresolved issue that can be solved. Although no quantum computer is yet complex enough to do the calculations that a classical computer can’t, the great progress continues.
