Sample-optimal tomography of quantum states
Jeongwan Haah, Aram W. Harrow, Zhengfeng Ji +2
It is a fundamental problem to decide how many copies of an unknown mixed quantum state are necessary and sufficient to determine the state. Previously, it was known only that esti…

A New Kind of Topological Quantum Order: A Dimensional Hierarchy of Quasiparticles Built from Stationary Excitations
Sagar Vijay, Jeongwan Haah, Liang Fu
We introduce exactly solvable models of interacting (Majorana) fermions in spatial dimensions that realize a new kind of topological quantum order, building on a model pr…

Localization from superselection rules in translation invariant systems
Isaac H. Kim, Jeongwan Haah
We study a translation invariant spin model in a three-dimensional regular lattice, called the cubic code model, in the presence of arbitrary extensive perturbations. Below a criti…
