QuantumCircuit.draw(output="text") is the quickest way to share a circuit in documentation.

from qiskit import QuantumCircuit
from qiskit.quantum_info import Statevector

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

print(Statevector(qc))

This prints amplitudes for the Bell state $\frac{1}{\sqrt{2}}(\lvert 00 \rangle + \lvert 11 \rangle)$ up to global phase conventions.

Large Statevector objects consume memory exponential in qubit count. Prefer tensor-network or hardware execution for large systems.
