Explain quantum computing in simple terms
Quantum computing is a type of computation that harnesses the collective properties of quantum states, such as superposition, interference, and entanglement, to perform calculations. The basic unit of information in quantum computing is the quantum bit or qubit, which unlike classical bits that are either 0 or 1, can exist in a superposition of states.
Can you give me a Python example of how to implement a quantum circuit using Qiskit?
from qiskit import QuantumCircuit, transpile
from qiskit.providers.aer import AerSimulator
# Create a quantum circuit with 2 qubits
qc = QuantumCircuit(2)
# Add a Hadamard gate to the first qubit
qc.h(0)
# Add a CNOT gate (controlled-X gate)
qc.cx(0, 1)
# Simulate the circuit
simulator = AerSimulator()
compiled_circuit = transpile(qc, simulator)
result = simulator.run(compiled_circuit, shots=1000).result()
# Print the results
counts = result.get_counts(qc)
print(counts)
