  Fast nonadiabatic control protocols known as shortcuts to adiabaticity have
found a plethora of applications, but their use has been severely limited to
speeding up the dynamics of isolated quantum systems. We introduce shortcuts
for open quantum processes that make possible the fast control of Gaussian
states in non-unitary processes. Specifically, we provide the time modulation
of the trap frequency and dephasing strength that allow preparing an arbitrary
thermal state in a finite time. Experimental implementation can be done via
stochastic parametric driving or continuous measurements, readily accessible in
a variety of platforms.
