Determination of All Unknown Pure Quantum States with Two Observables
Yu Wang
Efficiently extracting information from pure quantum states using minimal observables on the main system is a longstanding and fundamental issue in quantum information theory. Desp…
Pure State Tomography with Fourier Transformation
Yu Wang, Keren Li
Extracting information from quantum devices has long been a crucial problem in the field of quantum mechanics. By performing elaborate measurements, quantum state tomography, an im…
Quantum communication protocols by quantum walks with two coins
Yun Shang, Yu Wang, Meng Li +1
We introduce some new perfect state transfer and teleportation schemes by quantum walks with two coins. Encoding the transferred information in coin 1 state and alternatively using…
Pure state `really' informationally complete with rank-1 POVM
Yu Wang, Yun Shang
What is the minimal number of elements in a rank-1 positive-operator-valued measure (POVM) which can uniquely determine any pure state in -dimensional Hilbert space $\mathcal{H}…
