New paper in Nature Quantum Information

Last updated September 28, 2018 by Andrew Brown

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.
