MA3: Dissipative Quantum Simulation

Image

A central primitive in quantum simulation is ground- or thermal-state preparation and measurement of dynamical or static correlation functions. Reducing noise remains a central challenge to achieving practical quantum advantage in simulation. MA3 aims to develop strategies for using engineered dissipation for a range of tasks in quantum simulation, and to study the behavior and phases of mixed many-body states. While unwanted decoherence is a major hurdle in quantum simulation and computing, a carefully engineered dissipation can instead serve as a powerful tool. To advance towards useful quantum simulation, our work on dissipative quantum simulation in RQS Phase II is organized into three focus areas. 

• Focus area 3.1: Dissipative preparation of many-body states.
• Focus area 3.2: Open-system engineering and simulation.
• Focus area 3.3: Mixed-state phases of matter and quantum error correction.

We will advance the theory and practice of dissipative algorithms co-designed with available non-unitary operations.
