Polariton lasers emit coherent monochromatic light through a spontaneous emission process and show properties of Bose-Einstein condensation and superfluidity at room temperature. Emerging material systems for polariton lasers include organic molecules, transition metal dichalcogenides, perovskites, and liquid-crystal microcavities, which have potential applications in topological lasing, classical neuromorphic computing, and quantum information processing. Polaritonics, the study of strongly coupled light-matter states, offers advantages in classical and quantum information processing with full optical control and read-out capabilities.
Polariton lasers emit coherent monochromatic light through a spontaneous emission process. As a rare example of a system in which Bose-Einstein condensation and superfluidity are reported at room temperature, polariton lasers are interesting for fundamental research and offer potential for applications in classical and quantum information technologies. In the past 10 years, new material systems have emerged for polariton lasers, such as organic molecules, transition metal dichalcogenides, perovskites and liquid-crystal microcavities. In this Review, we discuss these emerging platforms in the context of applications in topological lasing, classical neuromorphic computing and quantum information processing. Polaritonics is the physics of strongly coupled light-matter states that studies condensates and superfluids of bosonic quasiparticles in solid-state systems. Coherent flows of exciton-polaritons can be used for classical and quantum information processing, offering advantages of full optical control and read-out.
