Quantum computing fundamentals

Quantum Computing Fundamentals: A Beginner’s Guide Quantum computing is one of the most exciting frontiers in technology today. While traditional computers have powered everything from smartphones to space exploration, quantum computers promise to solve problems that are currently impossible—or would take classical computers millions of years. But what makes quantum computing so different? Let’s break down the fundamentals. 1. Classical vs. Quantum Computing Traditional computers use bits, which can exist in one of two states: 0 or 1. Every app, photo, or website is built on these binary foundations. Quantum computers, on the other hand, use qubits (quantum bits), which behave according to the strange rules of quantum mechanics. 2. Key Principles of Quantum Computing Superposition Unlike classical bits, qubits can exist in multiple states at once—both 0 and 1 simultaneously. Imagine flipping a coin: instead of being heads or tails, a qubit can be in a mix of both until measured. This a...
