# Bloch sphere visualization using Cirq, ProjectQ, PyQuil

Is there a way to visualize the Bloch sphere using Cirq, ProjectQ, and/or PyQuil, as it is possible using plot_bloch_vector in Qiskit?

• TensorFlow Quantum, which primarily uses Cirq (since they are both owned by Google), used qutip.Bloch in this binary classification tutorial instead of any Cirq function, implying that Cirq does not have an equivalent.
• Rigetti, which owns PyQuil, used qutip.Bloch in this training material instead of any PyQuil function, and in this intro tutorial, implying that PyQuil does not have an equivalent.
• ProjectQ does not have any publicly visible Bloch sphere visualization tools in their Github, either. But their software already uses the IBM quantum experience, so I believe they would default to qiskit.plot_bloch_vector.
