Watch a conference presentation exploring fundamental concepts in quantum cryptography, focusing on one-way functions and their quantum analogues. Delve into the research findings of Morimae and Yamakawa as they investigate one-way state generators (OWSGs) and their relationship to quantum cryptographic primitives. Learn about the equivalence between OWSGs and quantum digital signatures, the implications of private-key quantum money schemes, and the connections to quantum pseudo one-time pad schemes. Examine the introduction of secretly-verifiable and statistically-invertible OWSGs and their equivalence to EFI pairs. Delivered at the 19th Conference on the Theory of Quantum Computation, Communication and Cryptography (TQC 2024) at OIST, Japan, this technical talk advances understanding of fundamental assumptions in quantum cryptography and their relationships to various cryptographic primitives.
