What Is Quantum Computing (quantum computers explained)

Quantum computers are machines that use quantum physics structures to store data and perform calculations. This can be a great help in certain tasks where it can go too far even for our greatest players.

Older computers, including Smartphones and laptops, insert data into the binary “bits” of about 0 or 1. In a quantum computer, the basic unit of memory is a quantum bit or qubit.

Qubits are made using body systems, such as an electron spin or a photon shape. These systems can be in many different settings simultaneously, an asset known as quantum superposition. Qubits can also be seamlessly connected using a quantum entanglement. The result is that a series of qubits can represent different objects simultaneously.

For example, eight pieces are enough for an old computer to represent any number between 0 and 255. But eight qubits is enough for a quantum computer to represent all numbers between 0 and 255 simultaneously. Hundreds of trapped qubits are not enough to represent more numbers than atoms in the universe.

This is where quantum computers come to an end more than in the past. In cases where there is a large number of possible combinations, quantum computers can look at them simultaneously. Examples include trying to find key features of a very large number or a path leading between two places.

However, there may be many situations where classical computers will still surpass quantum. So future computers can be a combination of both.

At present, quantum computers are very sensitive: heat, electromagnetic fields and collisions with air molecules can cause qubit to lose its quantum properties. This process, known as quantum decoherence, causes the system to be disrupted, and it occurs very quickly with many of the particles involved.

Quantum computers need to protect qubits from external interference, either by physically separating them, keeping them cool or installing them with carefully controlled power pipes. Additional qubits are required to correct errors entering the system.

Quantum computer vs superComputer

Difference Between Quantum and SuperComputer

Supercomputer is a system that operates at a high rate to I / O scale and transmits a very large number of active computer cycles per second. Quantum Computer is a computer that aims to use new quantum algorithms to speed up digital computation.

How much faster is a quantum computer than a supercomputer?

Light-Based Computer Exceeds High Speed ​​Computers. For the first time, the quantum computer made up of photons - light particles - outperformed even the most advanced computer drivers. ... In general, the ability to control photons such as qubits is a must for any large internet.
