Cooperative emission of photons from an ensemble of quantum dots (QDs) as superradiance can arise from the electronically coupled QDs with a coherent emitting excited state. This contrasts with superfluorescence (Dicke superradiance), where the coope

Founding Quantum Cryptography on Quantum Advantage, or, Towards Cryptography from $\mathsf{\#P}$-Hardness

Autor: Khurana, Dakshita, Tomer, Kabir

Recent oracle separations [Kretschmer, TQC'21, Kretschmer et. al., STOC'23] have raised the tantalizing possibility of building quantum cryptography from sources of hardness that persist even if the polynomial hierarchy collapses. We realize this pos
