Quantum computing: what it is and how it can revolutionize technology
Advertisements
THE quantum computing promises to rewrite the rules of information processing.
Imagine machines capable of solving problems intractable for today's supercomputers.
This new frontier of science and technology is moving from science fiction to tangible reality, shaping the future of countless industries.
Unlike classical computers that use bits (0 or 1), quantum systems employ qubits. A qubit can represent 0, 1, or a superposition of both simultaneously.
This intrinsic ability to explore multiple states at once is what gives quantum computers their exponential computational power.
Superposition and Entanglement: The Pillars of Quantum Capacity
THE superposition allows a qubit to exist in multiple states at the same time.

Already the entanglement links qubits in such a way that the state of one instantly influences the state of another, regardless of distance.
These exotic properties of quantum mechanics are the basis for solving complex problems.
Qubits can be implemented in a variety of ways, such as trapped atoms, ions, or even superconducting circuits.
The search for more stable qubits with a lower error rate is one of the main focuses of the research.
Quantum fragility requires extremely controlled environments, often at temperatures close to absolute zero.
Quantum Algorithms: New Paths to Solutions
Quantum algorithms like Shor's and Grover's offer dramatic speedups for specific problems.
Shor's algorithm, for example, can factor large numbers exponentially faster than any known classical algorithm. This has direct implications for modern cryptography.

Current Challenges
THE quantum computing requires precise control of the environment to maintain quantum coherence.
Decoherence, the loss of quantum state due to interaction with the environment, is a persistent obstacle.
Scalability, that is, increasing the number of qubits without compromising their quality, is also a bottleneck.
The Transformative Potential in Numbers
According to a report by McKinsey & Company, quantum computing has the potential to generate economic value of US$1.5 billion to US$1.5 billion annually by 2035.
This data reflects the magnitude of the expected impact on various sectors from an analytical perspective.
Think of a quantum computer's capabilities as a vast maze. A classical computer would have to test each path one at a time to find the exit.
A quantum computer, thanks to superposition, could explore multiple paths simultaneously, finding the solution much faster.
The 2025 Scenario
By 2025, we see a vibrant ecosystem around the quantum computing.
Large corporations and startups invest heavily in research and development, while universities train the next generation of quantum scientists.
Hardware is becoming more accessible, allowing more researchers to experiment and innovate.
Emerging Practical Applications
A concrete example is the area of materials science.
Researchers are using quantum processors to simulate the behavior of new catalysts, with the aim of creating more efficient and sustainable industrial processes.
Another example is the optimization of financial portfolios, seeking to maximize returns with lower risk.
Is the Future Quantum?
Faced with so much potential, it is undeniable that we are on the verge of a new technological era.

Frequently Asked Questions
What differentiates a quantum computer from a regular computer?
The main difference lies in the way they process information.
Classical computers use bits (0 or 1), while quantum computers use qubits, which can be in multiple states simultaneously thanks to superposition and entanglement.
When will quantum computing be available to the general public?
Large-scale, general-purpose quantum computing is still in development.
However, access to quantum systems for research and development purposes is already a reality through cloud platforms offered by several companies.
What are the biggest challenges in building quantum computers?
The main challenges include the decoherence (loss of quantum state), the need for quantum error correction and the scalability to build machines with an ever-increasing number of stable qubits.
Will quantum computing make current computers obsolete?
Not necessarily. It's more likely that quantum computing will complement classical computing, being used to solve specific problems that are intractable for current computers, while classical computers will remain ideal for everyday tasks.
Which industries will be most impacted by quantum computing?
Areas such as drug and materials discovery, finance, artificial intelligence, logistics, cybersecurity, and scientific research are expected to be profoundly transformed.
