quantum Hall state

[¦kwän·təm ′hȯl ‚stāt]
(cryogenics)
A kind of incompressible liquid state obtained by placing a two-dimensional electron gas, confined on the interface of two different semiconductors, in a strong magnetic field at low temperature. Also known as quantum Hall liquid.

Entanglement plays a central role for strongly correlated quantum many-body systems and is considered to be the root for a number of surprising emergent phenomena in solids such as high-temperature superconductivity or fractional quantum hall states. Entanglement detection in these systems is an important target of current research, but has so far remained elusive owing to the fine control required and high demands on statistical sampling.the goal of this project is to realize strongly correlated quantum systems close to the ground state using quantum annealing of ultracold fermionic atoms, and to study the character, strength and role of entanglement.
"In fractional quantum Hall states - a type of collective electron state observed only in two dimensional samples at very high magnetic fields - the quasiparticles are known to have precisely a rational fraction of the electron charge, implying that they are anyons," Young said in the release.
Under high magnetic field and at low temperatures, electronic interactions in a two-dimensional electron gas give rise to exotic, strongly correlated many-body quantum hall states. These states have been proposed for the implementation of new quantum circuits, for instance realizing topologically protected quantum computing.

Experimental input from studies of nematic quantum hall states and photoemission studies of weyl semimetals will provide feedback to this effort.
Since the discovery of fractional quantum hall states in 1982, The scientific community is awaiting further experimental advances: New types of strongly correlated states, Observation/manipulation of anyons.
It continues with edgeanyons , non-abelian quasiparticles residing on edges of abelian Quantum Hall states. Itends with open issues in the physics of the Quantum Hall Effect.We expect that this study will result in clear schemes for unquestionable experimentalidentification of Majorana fermions, new predictions for more of their measurable consequences,understanding of the feasibility of fractionalized phases in quantum wires, feasibleexperimental schemes for realizing and observing edge anyons, steps towards their classification,and better understanding of quantum Hall interferometry.
