What are the Quantum Computers?

How does a quantum computer work?

A quantum computer uses quantum mechanics phenomena such as “superposition” and “entanglement” to generate and control subatomic particles, such as electrons or photons, which are quantum parts also known as “qubits”, to provide many times more powerful processing power that can perform complex calculations that normally take It takes longer to solve even using the world's most powerful classic supercomputers. Quantum computing companies have embarked. The big challenge is to increase the number of “qubits,” the basic elements in quantum data processing, and to reduce the error rates that limit the complexity of quantum computing today. Whereas traditional computers store data in the form of “bits” that take only two values: either zero or one, qubits are able to store a much more complex state that combines zero and one together. This design gives quantum computers a much greater ability to solve computational problems simultaneously.

What are the techniques used?

There are many technologies used to build computers based on quantum technology such as superconducting qubits, ion traps, optical qubits, and spin points.

What are the benefits of quantum computing?

- Solve very important parts of problems in chemistry, materials science and financial services.

- Quantum chemistry simulations are especially important, because simulating atomic structures at the quantum level is impossible with the exception of simple molecular simulations. In addition, simulations can lead to real benefits such as cheaper fertilizers, better car batteries or better-performing solar panels.

- Accelerate the process of rescheduling flights after major disruptions such as hurricanes and snowstorms.

- A quantum computer could be used to better understand the universe.

- Innovating car batteries with higher capacities and at the same time being cheaper and reducing the harmful effects on the environment.

- Improving stock trading strategies and analyzing financial risks.

- Accelerate the search for new materials that can be used in the manufacture of flat screens used in devices such as televisions, telephones and tablets.

- Develop cryptography for hardware security.

- Improving artificial intelligence and using it in diagnosing diseases and detecting fraud.

in addition to many other benefits.

According to Accenture's Garrison: “Quantum devices are not going to replace conventional devices. But they will be used to solve very specific problems.” And these new technologies need some time to become accessible to everyone, so now you don’t need to rush to practice using them and learn how to deal with them. “Everything  in its due time is more beautiful”.
