Findings

Corrals act as quantum copying machines creating multiple images

New selection rules depend on geometry and candle location

Quantum images can be projected around corners in complex structures

Abstract

We study quantum imaging in a triangular quantum corral that is embedded in a superconducting host system with s-wave symmetry. We show that the corral acts as a quantum copying machine by creating multiple images of a quantum candle. We obtain new selection rules for the formation of quantum images that arise from the interplay of the corral's geometry and the location of quantum candles. In more complex corral structures, we show that quantum images can be projected "around the corner".
