A **quantum register** is a fundamental concept in quantum computing, analogous to a classical register in classical computing. It is a collection of quantum bits, or qubits, which are the basic units of quantum information. ### Key Features of Quantum Registers: 1. **Qubits**: Each quantum register consists of qubits. Unlike classical bits, which can be either 0 or 1, qubits can exist in a superposition of states.
