Quantum dynamics and fluctuating Hamiltonians: controlling many-body decoherence
ORAL
Abstract
Beating decoherence and dissipation is a core problem to develop quantum computation and quantum technologies. While tailoring the environment-system coupling has been proposed as a solution, techniques to engineer the required many-body decoherence in the laboratory remain to be developed.
Instead, the stochastic fluctuations naturally present on any platform can be harnessed as a ressource to tailor the dynamics. I will present a versatile scheme for the quantum simulation of the open dynamics of a many-body system embedded in an environment to which it couples via arbitrary many-body interactions. This approach exploits current technology for digital and analog quantum simulation of unitary dynamics harnessing noise as a resource, and can be readily implemented in various quantum experimental platforms such as trapped ions, superconducting circuits and cold atoms, thus finding widespread applications in quantum simulation and computation, quantum chemistry and biology.
