Higher Rank Matricial Ranges and Hybrid Quantum Error Correction
David W. Kribs, Ningping Cao, Chi-Kwong Li +3
We introduce and initiate the study of a family of higher rank matricial ranges, taking motivation from hybrid classical and quantum error correction coding theory and its operator…
Observing geometry of quantum states in a three-level system
Jie Xie, Aonan Zhang, Ningping Cao +7
In quantum mechanics, geometry has been demonstrated as a useful tool for inferring non-classical behaviors and exotic properties of quantum systems. One standard approach to illus…
Experimental self-characterization of quantum measurements
Aonan Zhang, Jie Xie, Huichao Xu +5
The accurate and reliable description of measurement devices is a central problem in both observing uniquely non-classical behaviors and realizing quantum technologies from powerfu…
Error correction schemes for fully correlated quantum channels protecting both quantum and classical information
Chi-Kwong Li, Seth Lyles, Yiu-Tung Poon
We study efficient quantum error correction schemes for the fully correlated channel on an -qubit system with error operators that assume the form , $σ_y^{\otim…
Determining system Hamiltonian from eigenstate measurements without correlation functions
Shi-Yao Hou, Ningping Cao, Sirui Lu +3
Local Hamiltonians arise naturally in physical systems. Despite its seemingly `simple' local structure, exotic features such as nonlocal correlations and topological orders exhibit…
