- Qubits: The fundamental unit of quantum information.
- Quantum gates: Operations that change the states of qubits, such as the Hadamard gate (H), which places qubits in a superposition, or the CNOT gate, which entangles qubits.
- Measurements: Extracting classical bits (0 or 1) from the qubit states after computations are completed.
Let's create a basic quantum circuit that puts a qubit into superposition using a Hadamard gate and then measures it.
