Lab

Build a quantum circuit in your browser, run it thousands of times, and watch the result form as a distribution. Superposition, entanglement and interference, hands on.

Qiskit code

from qiskit import QuantumCircuit, transpile
from qiskit_aer import AerSimulator

qc = QuantumCircuit(2, 2)
qc.h(0)
qc.cx(0, 1)
qc.measure([0, 1], [0, 1])

simulator = AerSimulator()
result = simulator.run(transpile(qc, simulator), shots=1000).result()
print(result.get_counts())

Runs entirely in your browser. This is an exact statevector simulation of an ideal, noiseless quantum computer — not a connection to quantum hardware, and not Qiskit. The Qiskit code above is generated for you to run yourself.
