Basics of Quantum Computing
What is Quantum Computing?
In simple terms, quantum computing leverages the principles of quantum mechanics—branching out from the physics that govern our everyday lives—to solve problems that are nearly impossible for traditional computers to handle.
Difference Between Quantum and Classical Computing
Unlike classical computers, which use bits as 0s or 1s, quantum computers use qubits. Qubits can exist as 0, 1, or both simultaneously, thanks to a phenomenon called superposition. This ability exponentially boosts their processing power.
Core Principles: Superposition, Entanglement, and Qubits
Superposition allows qubits to perform multiple calculations at once. Entanglement, another quantum property, means qubits can be interlinked, so the state of one instantly influences the other—no matter how far apart they are.
Key Developments in Quantum Computing by 2025
Breakthroughs in Hardware
Leading companies like IBM, Google, and startups such as Rigetti are rapidly developing quantum processors with higher qubit counts, bringing us closer to “quantum supremacy”—where quantum computers outperform classical ones.
