This paper presents the implementation of all-optical temporal logic gates using localized exciton polaritons (EPs) at room temperature. EPs, which are quasi-particle excitations formed by the strong coupling of photons and excitons, offer unique advantages such as strong nonlinearity, ultrafast reaction times, and the ability to form macroscopic quantum states. The authors demonstrate the full set of logical gate functionalities (AND, OR, and NOT) using a two-pulse excitation scheme, which precisely controls the interplay between the polariton condensate and the exciton reservoir dynamics. This approach eliminates the need for spatial flow, simplifies the fabrication process, and enables efficient information processing. The temporal degree of freedom is particularly advantageous for ultrafast switching, universality, and compatibility with other dimensional controls. The NOT gate, in particular, shows a response time of about 80 fs, making it one order of magnitude faster than previously reported polariton switches. The AND and OR gates are realized through stimulated amplification driven by two pumping laser pulses, with the relative time delay between the pulses controlling the gate functionality. This work opens new possibilities for building polariton logic networks in strongly coupled light-matter systems, contributing to the development of optical integrated circuits.This paper presents the implementation of all-optical temporal logic gates using localized exciton polaritons (EPs) at room temperature.
