Quantum multi-channel decoupling

Abstract

We study multiple-input multiple-output (MIMO) quantum systems and explore quantum decoupling techniques that can be used to facilitate the design of quantum networks. We provide a quantum state feedback control law to change the structure of a quantum system in order to decouple the multiple channels. We show that an MIMO quantum system can be decoupled as an aggregate of n separated single-input single-output (SISO) quantum systems from an input-output point of view. We also discuss the conditions under which quantum decoupling can be achieved. We illustrate our method with several qubit and atomic systems.

“…Fifteen journal [4,5,6,7,8,9,10,11,12,13,14,15,16,17,18] and thirteen peer-reviewed conference [19,20,21,22,23,24,25,26,27,28,29,30,31] papers have been published through the funding support period. Our research is multidisciplinary, and these papers appear in leading scientific journals and international conference proceedings across several disciplines including control theory and engineering, applied mathematics, physics, and bioengineering.…”
