Trotterization, Operator Scrambling, and Entanglement
Tianfeng Feng, Yue Cao, Qi Zhao
Operator scrambling, which governs the spread of quantum information in many-body systems, is a central concept in both condensed matter and high-energy physics. Accurately capturi…

Two measurement bases are asymptotically informationally complete for any pure state tomography
Tianfeng Feng, Tianqi Xiao, Yu Wang +6
One of the fundamental questions in quantum information theory is to find how many measurement bases are required to obtain the full information of a quantum state. While a minimum…
