This article discusses the significance of a recent discovery of an exotic quantum fluid in a device composed of atomically thin layers of semiconductors. This unusual fluid consists of bosonic excitons, which are bound pairs of electrons and holes. The study marks an important step toward stabilizing a Bose-Einstein condensate at high temperatures and under nearly equilibrium conditions. However, the described experiment has yet to demonstrate quantum coherence and superfluidity. The authors outline their vision for advancing the field by utilizing precise nanoscale manipulations to achieve quantum coherence. Finally, they propose applications of these findings for useful devices such as excitonic transistors, memory elements, and even quantum simulators.
