Query: Efficient simulation of open quantum systems coupled to a fermionic bath   We present and analyze the fermionic time evolving density matrix using
orthogonal polynomials algorithm (fTEDOPA), which enables the numerically exact
simulation of open quantum systems coupled to a fermionic environment. The
method allows for simulating the time evolution of open quantum systems with
arbitrary spectral densities at zero or finite temperatures with controllable
and certified error. We demonstrate the efficacy of the method towards the
simulation of quintessential fermionic open quantum systems including the
resonant level model and quantum dot coupled to an impurity and towards
simulating hitherto intractable problems in quantum transport. Furthermore, we
demonstrate significant efficiency gains in the computational costs by
performing simulations in the Heisenberg picture. Finally, we compare different
approaches for simulating finite-temperature situations and provide guidelines
for choosing between these approaches.
