Mitigating Correlated Noise in Quantum Machines

Abstract

Noise is ever-present in quantum devices and has been studied in detail for decades. However, typical noise models make rather strong assumptions to make the problem tractable. In reality, noise in quantum computers is more complex and is a major obstacle standing in the path of developing functional quantum technologies. This project has worked to translate theoretical advances into experimental reality. Several achievements and efforts have advanced this work. First was to characterize non-Markovian noise in real quantum computers. Second was development of a complete toolkit for non-Markovian noise characterization. Third was showing that multi-time non-Markovian correlations can be used to reduce the noise of any quantum computer. And fourth was uncovering that just like in space, entanglement in time can also have a nontrivial manifestation.
