Applications of Bit Commitments in a Quantum World

Explore the applications and implications of bit commitments in quantum cryptography through this 39-minute conference talk by James Bartusek from UC Berkeley. Delve into the construction of protocols with certified everlasting security using standard bit commitments as a minimal assumption. Learn about pseudorandom quantum states, oblivious transfer, and the novel concept of everlasting security transfer. Gain insights into how bit commitments enable enhanced functionality and security in quantum cryptography compared to classical methods. Understand the significance of this research, which is based on joint work with Dakshita Khurana, presented at the Minimum Quantum Assumptions for Cryptography Workshop hosted by the Simons Institute.
