Quantum programming languages

Definition

Quantum programming languages are specialized languages designed for writing programs that run on quantum computers, taking advantage of quantum mechanics principles like superposition and entanglement. These languages enable programmers to create quantum algorithms that can solve complex problems much faster than classical algorithms by expressing operations on quantum bits (qubits) directly. They also facilitate the development of applications in fields such as cryptography, optimization, and machine learning.
