Quantum Computing: A Scientific Revolution That Will Change the Future of the World
Introduction
With each generation, technologies emerge that turn the tables and reshape our understanding. As the twenty-first century dawns, humanity has begun to approach one of the greatest transformations in the history of technology: the quantum computer. This amazing technology is not just a faster version of a traditional computer, but represents a quantum leap in the way computers think and process data.
But when did the idea of quantum computing emerge? Who owns it? How realistic is this advancement? Will it really change the computing world as we know it?

Idea and Origin: Beginning at the Heart of Physics
The idea of quantum computing first emerged in the 1970s and 1980s, when scientists began to notice that the laws governing small particles (such as electrons and photons) were completely different from those governing the classical world.
In 1981, In 1991, the famous physicist Richard Feynman presented a new idea at a scientific conference in which he said:
"We can't simulate quantum physics with a classical computer... so maybe we should build a quantum computer."
This began the serious search for a device that could use the laws of quantum mechanics to perform calculations that a conventional computer couldn't.
What is the difference between a traditional computer and a quantum computer?
The main difference between classical computers and quantum computers lies in the basic unit of data:
In traditional computers, data is stored using bits, which take on only two values: 0 or 1.
In quantum computers, what is known as a qubit is used, a unit that can be 0 and 1 at the same time, thanks to a phenomenon known as quantum superposition.
In addition, a quantum computer takes advantage of another phenomenon called quantum entanglement, which allows qubits to communicate and influence each other in an amazing and instantaneous way, even if the distances between them are large.
As a result, a quantum computer can perform very complex operations at super-fast speeds compared to any classical computer.
Who is working on developing a quantum computer today?
Thanks to the great advances in technology, many global companies and institutions have begun to enter the field of quantum computing. Here is a list of the most famous players in this field:
🔹 IBM
One of the first companies to embrace the idea and deliver the first cloud-based quantum computer that can be used by researchers around the world.
IBM has released machines with 5, 16 and 50 qubits and is currently aiming to reach 1000 qubits by 2025.
🔹 Google
In 2019 Google announced that it had achieved so-called “quantum supremacy” after its quantum machine was able to perform a calculation in 200 seconds, while the same operation on the most powerful conventional computer would take more than 10,000 years.
🔹 Microsoft
It is focused on developing a complete software environment for quantum computing, with support for building and developing quantum algorithms through its Azure Quantum platform.
🔹 D-wave
A Canadian company specializing in specialized quantum computing (Quantum Annealing), focused on solving problems related to performance optimization and artificial intelligence.
🔹 Amazon, Intel, Honeywell, Rigetti
They have all entered this field and are working on the development of quantum devices and platforms, independently or in collaboration with research institutes.
In total, today there are more than 100 companies and research institutions working on the development of quantum computing and its applications in various fields.
Will quantum computers change the future of technology?
Answer: Yes, radically.
Quantum computers will revolutionize several areas, including:
Artificial Intelligence and Deep Learning
Quantum computers will help train AI models at unprecedented speed, meaning intelligent robots and applications will be more accurate and realistic.Medicine and Drug Design
This will allow scientists to analyze complex genes and precisely simulate drug interactions with cells, speeding up the development of treatments for diseases such as cancer and Alzheimer's.Cybersecurity
A quantum computer is capable of deciphering traditional encryption systems, which will push the world to develop new encryption systems that are resistant to quantum technologies.Economics and Trade
It can accurately analyze financial markets and predict crashes or investment opportunities at lightning speed.
Are we ready for this revolution?
Despite all the excitement, quantum computers are still in their infancy and face many challenges, such as:
Difficulty in maintaining qubit stability.
Low temperature is required
