  Simulating the dynamics of open quantum systems is essential in achieving
practical quantum computation and understanding novel nonequilibrium behaviors.
However, quantum simulation of a many-body system coupled to an engineered
reservoir has yet to be fully explored in present-day experiment platforms. In
this work, we introduce engineered noise into a one-dimensional ten-qubit
superconducting quantum processor to emulate a generic many-body open quantum
system. Our approach originates from the stochastic unravellings of the master
equation. By measuring the end-to-end correlation, we identify multiple steady
states stemmed from a strong symmetry, which is established on the modified
Hamiltonian via Floquet engineering. Furthermore, we find that the information
saved in the initial state maintains in the steady state driven by the
continuous dissipation on a five-qubit chain. Our work provides a manageable
and hardware-efficient strategy for the open-system quantum simulation.
