In this work, we study the consequences of entanglement-assistance (EA) for randomness generation in the semi-DI framework based on energy constraints introduced in (van Himbeeck et al., Quantum 1, 33 (2017)). We show that, given an energy bound $\omega$, the minimum min-entropy that non-EA honest devices can certify decreases when entanglement between the prepare and measurement boxes (of the devices prepared by Eve) is allowed.

In this work, we present a new measurement-device-independent QRNG developed within Quside based on operating a vertical cavity surface emitting laser (VCSEL) in a gain-switching manner. We prove security in the finite-size regime using the EAT and obtain positive rates for as low as 7x10^4 rounds.
