Logical Cooling for Noise Reduction in Analogue Quantum Simulation

Analogue quantum simulation is arguably the most promising near-term application of quantum computing. However, analogue simulators are susceptible to noise, and it is not known if realistic noise destroys their computational power. Here, we report our progress using a technique to remove errors in the computational basis of the system, without resorting to a full error correcting scheme, to both measure and increase an analogue quantum simulator's robustness to noise.
