Joint measurability for binary quantum measurements
Abstract: The ability to perform two measurements simultaneously is not granted by quantum mechanics. In this talks, I will introduce several notions, such as joint measurability and coexistence of m...

Succinct Perfect Zero-knowledge for MIP*
Abstract: In the recent breakthrough result of Slofstra and Mastel (STOC'24), they show that there is a two-player one-round perfect zero-knowledge MIP* protocol for RE. We build on their result to s...

Quantum Journal Club： Antiferromagnetic Spinor Condensates in a Two-Dimensional Optical Lattice
Abstract: We experimentally demonstrate that spin dynamics and the phase diagram of spinor condensates can be conveniently tuned by a two-dimensional optical lattice. Spin population oscillations and...
