Model of Coupled Quantum Memristors Based on a Single Trapped 171Yb+ Ion

“…The theoretical concept of the trapped-ion quantum memristor was presented in [10]. We briefly describe it.…”

“…In this case, the state parameter can be changed by selecting the duration and/or amplitude of laser pulses in an arbitrary manner. To implement the quantum memristor experimentally, one can change the s value (according to a certain law [10]) during a certain time interval and ensure feedback to change the value for the following interval .…”

“…In the second level selection method, hyperfine sublevels of the level can be defined as and [10]. The energy difference between these states is 3.6 GHz.…”

“…To date, the implementation of quantum memristors has been proposed on several platforms: quantum photonics [4,5], superconducting circuits [3,[6][7][8][9], ion traps [10], and circuits based on the features of the light-matter interaction [11,12]. Some of them were implemented experimentally [13,14].…”

“…We have recently proposed a quantum memristor based on ultracold ions trapped in Paul traps [10]. It was shown that the dependence of the output signal on the input one is hysteretic at certain parameters of laser pulses, which ensure the variation of the population of selected ion levels.…”
