Abstract

This paper presents a implementation for a controlled-iSWAP gate working by applying a single lux pulse. The gate can be implemented using superconducting circuits or other systems which natively features an XY-interaction. The paper also discuss a quantum circuit for probabilistic exponentiating the iSWAP gate and other non-Hermitian gates.
