- Abstract: The problem of establishing Bell and Greenberger-Horne-Zeilinger states
between faraway places or distant nodes of a circuit is a difficult and an
extremely important one, and a strategy which addresses it is entanglement
percolation. We provide a method for attaining the end through a quantum
measurement strategy involving three-, two-, and single-qubit measurements on a
single-layer honeycomb lattice of partially entangled pure bipartite entangled
states. We then move over to a double-layered lattice, and introduce
entanglement percolation on that lattice under a realistic restriction on local
quantum operations and classical communication allowed on the nodes of the
lattice. When applied to a single-layered honeycomb lattice, our strategy would
call for less noise effects in an actual realization than when the same
phenomenon is attained via existing methods. Moreover, for the double-layered
honeycomb lattice, we report advantage of quantum entanglement percolation over
classical entanglement percolation under the realistic restriction.

Storing quantum information requires battling quantum decoherence, which results in a loss of information over time.
To achieve error-resistant quantum memory, one would like to store the information in a quantum superposition of degenerate states engineered in such a way that local sources of noise cannot change one state into another.
We show that this platform also allows to detect and correct certain types of errors en route to the goal of true error-resistant quantum memory.

We propose a scheme to realize bosonic fractional quantum Hall conductance in shaken honeycomb optical lattices.
By filling the lattice at 1/4 with identical bosons under Feshbach resonance, two degenerate many-body ground states share one Chern number of 1.
We prove that the fractional quantum Hall state can be prepared by adiabatically turning on the lattice shaking, and the fractional conductance is robust in the shaken lattice.

Purifying entanglement resources after their imperfect generation is an indispensable step towards using them in quantum architectures.
Here we depart from the typical purification paradigm for multipartite states explored in the last twenty years.
We find that smaller sacrificial' states, like Bell pairs, can be more useful in the purification of multipartite states than additional copies of these same states.
