a Coupling schemes of chiral molecules with L and R handedness. Identical drivings result in a difference of π in the overall phase of the loop, indicated here as different couplings (±Ωq) between the states of 1 and 3. b Pulse sequence for the driving fields Ωp(t), Ωs(t), and ±Ωq(t). c Measured population P3 versus time and pulse area Aπ for L (left panel) and R (right panel) handedness, where the initial state \(\left|{\psi }_{0}\right\rangle =\left|1\right\rangle\). The maximum population contrast is obtained when A ≈ 1.23 (indicated by the white dashed lines). t = 0 corresponds to the moment when the ±Ωq pulse reaches its maximum magnitude. d The population P3 as a function of time for A = 1.23, showing that the transfer to the state of three is nearly perfect for L handedness, but completely suppressed for R handedness. The spheres illustrate the trajectories of state evolution in the Majorana representation by mapping the qutrit states to two points on the spheres42 (see Supplementary Note 4).
