Quantum Computing is a type of computing that uses the principles of quantum mechanics—the physics of the very small—to process information in ways that classical computers cannot.

Entanglement

Qubits can be linked so that changing one instantly affects the other, even at a distance.

Interference

Quantum states can amplify correct answers and cancel out wrong ones.

Quantum computers

use qubits — each qubit can be 0, 1, or both at the same time (thanks to a property called superposition).

Quantum Information Processing

What Is Quantum Computing (Simply Put)?

Traditional computers use bits, which are either 0 or 1.

Quantum computers use quantum bits (qubits), which can be 0, 1, or both at the same time (thanks to quantum principles like superposition and entanglement).

This allows quantum computers to process massively complex problems that are practically impossible for classical computers.

Why Quantum Computing Matters:

Quantum computers can solve problems that would take millions of years for today’s fastest supercomputers. They’re not “faster PCs”—they’re different machines for specific, complex problems, such as:

• Cryptography (breaking RSA encryption)

• Drug discovery & molecular modeling

• Optimization problems (e.g., in logistics or finance)

• Climate modeling

• AI and machine learning

Who’s Leading in Quantum Computing?

• IBM Quantum – Open-access quantum computers (Qiskit)

• Google Quantum AI – Achieved "quantum supremacy" in 2019

• Microsoft Azure Quantum – Quantum cloud services

• D-Wave – Quantum annealing systems for optimization

• IonQ, Rigetti, PsiQuantum – Quantum hardware startups
