Operator extension of strong subadditivity of entropy
Isaac H. Kim
We prove an operator inequality that extends strong subadditivity of entropy: after taking a trace, the operator inequality becomes the strong subadditivity of entropy.
Perturbative analysis of topological entanglement entropy from conditional independence
Isaac H. Kim
We use the structure of conditionally independent states to analyze the stability of topological entanglement entropy. For the ground state of quantum double or Levin-Wen model, we…
Determining the structure of real-space entanglement spectrum from approximate conditional independence
Isaac H. Kim
We study the ground state of a gapped quantum many-body system whose entanglement entropy can be expressed as , where are some constants and $…
3D local qupit quantum code without string logical operator
Isaac H. Kim
Recently Haah introduced a new quantum error correcting code embedded on a cubic lattice. One of the defining properties of this code is the absence of string logical operator. We…
