What is Quantum Computer? How does it work?

We have compiled information about quantum computing . When the subject enters the quantum field, it becomes very difficult to understand and visualize this computer. Of course, the concepts of quantum physics make things more difficult. It is now a fact that a new era will begin with these computers. Good reading.


What is Quantum Computer?

what is a quantum computer

Quantum computers are faster than traditional computers than we would imagine. It is called computers that take power from the superposition and entanglement elements of quantum physics and process information in very fast and unique ways. It has faster and more efficient processing power than any computer when processing data.

With the development of quantum physics, the idea of using quantum computers also made progress. It was conceived by Nobel physicist Richard Feynman in the early 1980s to solve and simulate the complex and long-running equations of quantum physics. In 1981, Paul Beniof created the theory of quantum computing based on Max Planck’s ideas.


Quantum Computing and Computing

Quantum computers are computers that can run very difficult quantum algorithms much, much faster than the processor of a standard computer. In doing so, it does so using the principles of quantum mechanics, which are responsible for the operation of large systems such as photons, atoms and electrons, and elementary particles, such as superconducting circuits. It takes advantage of the principle that subatomic particles exist in more than one state.


How Quantum Computers Work

how quantum computers work

It was developed with the principles of quantum theory, which tries to study energy and matter at the atomic and subatomic level. Quantum bits, also known as qubits, and the superposition, that is, subatomic particles’ ability to exist in more than one state, are used when processing in quantum computers. Qubits are very delicate and very difficult to care for. They react to even the smallest change in their environment and may lose their data. These units, called qubits, store information.

Quantum computers do not use bit units of standard computers, they use these units called qubits. Quantum computers do not use 1 or 0 transistors like conventional computers. Unlike conventional computers, whose information is only 0 and 1, a quantum computer can also be a qubit. Both 0 and 1 have a superposition. This superposition also parallelizes operations by performing safe calculations and transformations.


Some Problems of Quantum-Based Computers

Because qubits are fragile, their interaction with the external environment causes them to collapse and lose their quantum properties in a process known as dissonance. If this process occurs before the algorithm finishes running, all the information stored in the qubits is lost. Meanwhile, it becomes difficult to keep the other qubits consistently. For these reasons, the quantum computer must be isolated from the external environment. The stricter the isolation of these cold systems, which are protected from the outside world, the more difficult it is to communicate and control with the computer.


Quantum Computing Superiority

quantum supremacy

Quantum supremacy is used to indicate that the speed and power of a quantum computer is higher than that of a standard computer. This strength is such that a quantum computer can crack almost any encryption of transactions on the Internet. For this, it needs millions of qubits. Today, quantum computers have 100 qubits. For example, it was said that a Chinese team solved a nine-year solution in an hour with a quantum computer.
