(a) Memory capacity for different inter-spin couplings \(J^k_{i,j}=(i+j)^k/c_k\). The maximum capacity has a non-monotonic behaviour in k, while the location of the maximum shifts towards larger \(\Delta t\) in increasing k. (b) Memory accuracy at the short time interval. The interval \(\Delta \) is too short for \(k=6\) while the other setups exhibit the long but inaccurate memory. (c) At long time intervals the setups exhibit the short but accurate memory. Higher k values result into a longer but inaccurate of memory.
