On the Impossibility of Simulation Security for Quantum Functional Encryption

Functional encryption is a powerful cryptographic primitive that enables fine-grained access to encrypted data and underlies numerous applications. Although the ideal security notion for FE simulation security has been shown to be impossible in the classical setting, those impossibility results...

Certified Randomness Amplification by Dynamically Probing Remote Random Quantum States

Cryptography depends on truly unpredictable numbers, but physical sources emit biased or correlated bits. Quantum mechanics enables the amplification of imperfect randomness into nearly perfect randomness, but prior demonstrations have required physically co-located, loophole-free Bell tests,...
