Quantum system characterisation techniques represent the front-line in the identification and mitigation of noise in quantum computing, but can be expensive in terms of quantum resources and time to repeatedly employ. Another challenging aspect is that parameters governing the performance of various operations tend to drift over time, and monitoring these is hence a difficult task. One of the most promising characterisation techniques, gate set tomography (GST), provides a self-consistent…

Demonstration of non-Markovian process characterisation and control on a quantum processor

This work develops a framework for characterising non-Markovian dynamics in quantum systems and experimentally test it on multi-qubit superconducting quantum devices, showing it leads to superior quantum control and extension of coherence time by effective decoupling from the non- Markovian environment.
