Reconfigurable ultrafast perovskite polariton logic gates via nonlinear dynamics
Yuyang Zhang, Zhuoya Zhu, Xin Zeng +14
Exciton-polaritons provide a great platform for developing ultrafast all-optical logic gates for quantum and optical chips. However, progress toward practical polariton logic remai…

All-optical and ultrafast control of high-order exciton-polariton orbital modes
Yuyang Zhang, Xin Zeng, Wenna Du +14
Exciton-polaritons flows within closed quantum circuits can spontaneously form phase-locked modes that carry orbital angular momentum (OAM). With its infinite set of angular moment…
