Let’s explore how quantum computing works, why it’s creating a buzz, and the many fields it’s already transforming.
What is Quantum Computing?
Quantum computing is a branch of computer science and physics that leverages quantum mechanics to perform calculations beyond the reach of traditional systems. Instead of bits, quantum computers use qubits, which exist in multiple states at once thanks to the principles of superposition and entanglement.
How Quantum Bits (Qubits) Differ from Classical Bits?
In classical computing, bits are binary. A bit can either be a 0 or a 1. Simple enough, right? But quantum computing operates on qubits, which can be 0, 1, or both at the same time due to superposition. This characteristic allows quantum machines to process massive datasets at astonishing speeds.
Another concept—entanglement—enables qubits that are entangled to affect each other’s states, no matter how far apart they are. This interconnectedness can lead to extraordinary computational powers, especially in problems where variables are deeply intertwined.
