Figure 2: Using the protocols developed by Kastryano et al. [1], dissipative quantum information processing can be performed by engaging Markov processes in a precisely time-ordered fashion. Imagine a relay race in which one runner hands a baton to a second runner. In a similar way, quantum states evolving according to Liouville operators $L1$ and $L2$ can trigger each other. In this example runner $L1$ starts at $t0$ and ends at $t1$, where runner $L2$ takes over until $t2$ (shown as the finish line, but this process could be repeated over more sequences). Normally, dissipative evolutions cannot be timed in that way, but the protocols developed by Kastoryano et al. allow one to perform dissipative operations sequentially at specific points in time during well-defined time windows.
