Fig. 5: Wilson line.
From: Wilson loop and Wilczek-Zee phase from a non-Abelian gauge field
Absolute values of measured Wilson line ∣W(ϕ)∣ for open paths with variable path length characterized by rf phase range ϕ. The theory curve (solid line) is also shown. The inset illustrates the control sequence for Wilson line measurement of a segment from q0 to qf on a circular loop. After preparing one of the eigenstates at q0, the rf phase ϕA is ramped from 0 to ϕ. The red and green curves represent the pulse controls for the state preparation and the state mapping for the read-out. The laboratory parameters are ΩA = ΩB = h × 1.4 kHz.
