Quantum Computing: What Is It — and Why It Matters Now

Saturday, November 29, 2025

Quantum computing is not just the next step in computing: it is a fundamentally different paradigm. Unlike traditional computers, which use bits that are either 0 or 1, a quantum computer uses quantum bits — qubits. These qubits can exist in superposition (both 0 and 1 simultaneously) and can become entangled with one another, meaning their states become deeply linked even when separated.
