The paper establishes that the existence of many-time secure uncloneable encryption (UCE) can be shown to follow from relatively weak assumptions, such as the existence of many-time secure symmetric key encryption or pseudorandom unitaries, within the framework of quantum cryptography.
The paper introduces stronger cryptographic notions, quantum localization and trajectory verification, to robustly certify a quantum entity's position and movement through spacetime.
The paper constructs strong cryptographic primitives, including key agreement and oblivious transfer, directly from classical tests of anti-commutation (ToNC) on quantum devices, while also developing new post-quantum hardness amplification tools.
