Introduction
Quantum computing is no longer just a theoretical concept—it’s rapidly becoming a practical technology with groundbreaking applications. Unlike classical computers that rely on binary bits (0s and 1s), quantum computers use qubits, which leverage superposition and entanglement to perform complex calculations at unprecedented speeds.In this article, we’ll explore the most promising quantum computing applications, from cryptography to drug discovery, and how industries are preparing for this revolutionary shift.
What Makes Quantum Computing Different?
Before diving into applications, let’s briefly understand why quantum computing is transformative:
