In classical cryptography, it has long been known that the existence of one-way functions is the minimum assumption. However, in quantum cryptography, where quantum computation and communication are possible, several recent studies have shown that it is not necessarily the case. This workshop will explore foundations of quantum cryptography without one-way functions to answer the ultimate open problem, "what is the most fundamental assumption in quantum cryptography?"

Speakers: Tomoyuki Morimae (Kyoto University), Prabhanjan Ananth (UC Santa Barbara), Andrea Coladangelo (University of Washington), James Bartusek (UC Berkeley), and Jiahui Liu (University of Texas at Austin)
