OPEN Quantum control using quantum memory

This paper proposes a new quantum numerical scheme to control the dynamics of a quantum walker in a two-dimensional space-time grid using quantum memory. By encoding the control scheme into the initial state of the system (walker + memory), the authors demonstrate the ability to precisely control the walker's mean trajectory and variance without needing continuous adjustments to the evolution operator. This approach offers potential for simulating complex physics models on quantum devices and provides a new avenue for simulating aspects of quantum field theories, particularly on curved manifolds.
