Extended Data Fig. 3: Vector control with the photonic link.
From: Control and readout of a superconducting qubit using a photonic link
Ramsey oscillation driven by the photonic link, as a function of the phase θ of the second π/2 pulse (same set-up as Fig. 2d). Data (dots) follow a clean sinusoidal dependence (line). \({R}_{x}^{{\rm{\pi }}/2}\) denotes a π/2 qubit rotation around the x axis and \({R}_{\theta }^{{\rm{\pi }}/2}\) denotes a π/2 qubit rotation around an axis with a variable angle θ within the x–y plane. qb, qubit; cav., cavity.
