We propose quantum simulations of 1+1D radial sections of different black hole spacetimes (Schwarzschild, Reissner-Nordstr\o{}m, Kerr and Kerr-Newman), by means of a dc-SQUID array embedded on an open transmission line. This is achieved by reproducing the effective speed of light in the 1+1D sections of the spacetime with the propagation speed of the electromagnetic field in the simulator, which can be modulated by an external magnetic flux. We show that the generation of event horizons -- and therefore Hawking radiation -- in the simulator could be achieved for non-rotating black holes, although we discuss limitations related to fluctuations of the quantum phase. In the case of rotating black holes, it seems that the simulation of ergospheres is beyond reach.

Robustness of analogue Hawking radiation in cavities with moving boundaries
Thermal Hawking-like radiation in moving-mirror cavities is robust only for selected expanding configurations and low frequencies; all other configurations tested show non-thermal spectra.

Analogue simulation of quantum gravity black hole models in a dc-SQUID array
The authors derive the magnetic flux patterns a dc-SQUID array would need to simulate light propagation in a bouncing black-hole-white-hole spacetime, and argue the downstream configuration is the more practical one.
