Quantum Computing Basics for Developers Quantum computers use qubits that can be 0 and 1 at the same time, thanks to superposition. Gates act on these states to change them, and measurements reveal results with probabilities. For developers, this means a new way to think about problems, not just faster code. What is a qubit? A qubit is the tiny unit of a quantum computer. It can represent 0, 1, or both at once. When you measure a qubit, it collapses to a definite value, so repeat runs give different results according to their probabilities. Two or more qubits can be entangled, creating correlations that do not exist in classical systems. ...
