Quantum simulation of Unruh-DeWitt detectors with nonlinear optics

Eugene Adjei, Kevin J. Resch, Agata M. Brańczyk

We propose a method for simulating an Unruh-DeWitt detector, coupled to a 1+1-dimensional massless scalar field, with a suitably-engineered ${\chi }^{(2)}$ nonlinear interaction. In this…
