Query: Robust measurements of n-point correlation functions of
  driven-dissipative quantum systems on a digital quantum computer   We propose and demonstrate a unified hierarchical method to measure n-point
correlation functions that can be applied to driven, dissipative, or otherwise
non-equilibrium systems. In this method, the time evolution of the system is
repeatedly interrupted by interacting an ancillary qubit with the system
through a controlled operation, and measuring the ancilla immediately
afterwards. We discuss robustness of this method versus ancilla-enabled
interferometric techniques (such as the Hadamard test), and implement the
method on a quantum computer in order to measure single-particle Green's
functions of a driven-dissipative fermionic system. This work shows that
dynamical correlation functions for driven-dissipative systems can be measured
with near-term quantum computers.
