CTAMOP research fellow Ricardo Puebla has published an article in the prestigious journal Nature Quantum Information.

The key finding of the work is that dynamics of nonlinearly-interacting light-matter systems can be described using just linear terms and spin rotations. 

The article draws a connection between a generic model involving nonlinear interactions (i.e., emission/absorption of many photons at the same time from the same particle) with a simpler model involving just linear terms and spin rotation. This connection allows the dynamics of nonlinearly-interacting systems to be simulated without actually including nonlinearities. 

Such models describe many disparate quantum systems, and are thus both of fundamental and technological interest.
