Quantum Fire with Delegated Cloning

Quantum fire is a recently introduced cryptographic primitive consisting of efficiently preparable quantum states, called flames, that admit efficient cloning but resist efficient telegraphing, namely reconstruction via classical communication without preshared entanglement. In all prior...

Public-Key Quantum Fire and Key-Fire from Classical Oracles

Quantum fire was recently formalized by Bostanci, Nehoran and Zhandry STOC 25. This notion considers a distribution of quantum states that can be efficiently cloned, but cannot be converted into a classical string. Previously, work of Nehoran and Zhandry ITCS 24 showed how to construct quantum fi...
