Dissipative Universal Lindbladian Simulation

Understand

It is by now well understood that quantum dissipative processes can be harnessed and turned into a resource for quantum-information processing tasks.

• In this paper we demonstrate yet another way in which this is true by providing a dissipation-assisted protocol for the simulation of general Markovian dynamics.
• More precisely, we show how a suitable coherent coupling of a quantum system to a set of Markovian dissipating qubits allows one to enact an effective Liouvillian generator of any Lindbladian form.
• This effective dynamical generator arises from high-order virtual-dissipative processes and governs the system dynamics exactly in the limit of infinitely fast dissipation.
