Title: Learning nonlinear input-output maps with dissipative quantum systems

Abstract :

In this seminar, I will describe a theoretical framework for learning of nonlinear input-output maps with fading memory by dissipative quantum systems, as a quantum counterpart of the theory of approximating such maps using classical dynamical systems. 

Such a theory can provide the foundation for harnessing of dissipative quantum systems for applications such as nonlinear systems modelling and signal processing. In particular, the theory identifies the properties required for a class of dissipative quantum systems to be universal, in the sense that any input-output map with fading memory can be approximated arbitrarily closely by an element of this class. 

We then introduce an example class of dissipative quantum systems that is probably universal. Some numerical examples will be presented.

The seminar is based on joint work with J. Chen (Quantum Information Processing, 18(7):198 (2019)/arXiv:1901.01653)
