= Quantum complexity theory
{wiki=Quantum_complexity_theory}
Quantum complexity theory is a branch of theoretical computer science that studies the complexity of problems within the framework of quantum computation. It explores how quantum algorithms can solve problems more efficiently than classical algorithms and seeks to classify problems based on their computational hardness in the quantum setting. Here are some key concepts and topics in quantum complexity theory: 1. **Quantum Computation Model**: Quantum complexity theory is grounded in the model of quantum computation, where computation is performed using quantum bits (qubits).
