CsPbBr3 perovskite quantum dots are bright, solution-processable nanocrystal emitters with size-tunable color and high oscillator strength. Furthermore, they can be fabricated and processed in a cheap and facile way. We investigate electric-field tuning of single dots through the quantum-confined Stark effect to minimize exciton fine-structure splitting and tune separate emitters into resonance with each other. This opens up possibilities of creating entangled photon pairs of super- and subradiance with perovskite quantum dot based photonic devices.
