A quantum computing approach to electromagnetic wave propagation in cold magnetized plasmas
Abstract: Following recent advances in quantum technologies, there is a sense of optimism that, in the near future, quantum computers will provide a paradigm shift in scientific computations and simulations. The admissible operations in a quantum computer are restricted to unitary transformations, as dictated by the evolution dynamics of closed quantum systems. However, in plasma physics, physical processes of interest are dissipative and nonlinear, thereby posing a serious challenge to developing algorithms suitable for implementation and simulation into a quantum computer. In this talk, we address the effect of collisional dissipative processes in the quantum simulation of electromagnetic wave propagation in a magnetized plasma. Within the cold plasma approximation, where the thermal motion of the charged particles is neglected, the dissipative term in Maxwell’s equations takes on a diagonal form. This allows us to efficiently implement dissipation using the Linear Combination of Unitaries (LCU) technique. By leveraging the LCU method, we demonstrate that the overall success probability of the simulation algorithm is directly related to the physical time scales of dissipation and, consequently, to the resources required for the quantum implementation.
