Line Plot from Scientific Research

Spin and valley pulsing protocol for (1, 1) (0, 2) with corresponding exemplary time traces. The gate position for each phase is marked in b . Starting from the (0, 1) state in unload (U), we pulse to the load position (L) slower than the dot–lead tunnel rate to prepare a (1, 1) state. We then pulse to the anchor point (A) slower than the line-bandwidth of the order of 100 s, before pulsing to the read location (R). In the read phase, the system is energetically preferred to transfer to (0, 2), but is forbidden to do so by mismatching quantum numbers between triplet (1, 1)T and singlet (0, 2)S, unless a relaxation event occurs (indicated by purple arrows in the time traces).
