Single-qubit state tomography.
cirq.circuits.Circuit, repetitions: int = 1000 ) ->
The density matrix of the output state of a circuit is measured by first doing projective measurements in the z-basis, which determine the diagonal elements of the matrix. A X/2 or Y/2 rotation is then added before the z-basis measurement, which determines the imaginary and real parts of the off-diagonal matrix elements, respectively.
See Vandersypen and Chuang, Rev. Mod. Phys. 76, 1037 for details.
