  Shortcut engineering consists of a class of approaches to rapidly manipulate
physical systems by means of specially designed external controls. In this
Letter, we apply these approaches to run-and-tumble particles, which are
designed to mimic the chemotactic behavior of bacteria and therefore exhibit
complex dynamics due to their self-propulsion and random reorientation, making
them difficult to control. Following a recent successful application to active
Brownian particles, we find a general solution for the rapid control of 1D
run-and-tumble particles in a harmonic potential. We demonstrate the
effectiveness of our approach using numerical simulations and show that it can
lead to a significant speedup compared to simple quenched protocols. Our
results extend shortcut engineering to a wider class of active systems and
demonstrate that it is a promising tool for controlling the dynamics of active
matter, which has implications for a wide range of applications in fields such
as materials science and biophysics.
